7、/13/2007 21:01:52 MDTNo reproduction or networking permitted without license from IHS -,-,- Testing methods for mine water and/or waste water 1 Scope This Japanese Industrial Standard specifies the testing method for mine water and/or waste water of the mines (including attached facilities, but excl
8、uding coal and petroleum mines), hereafter referred to as “mine water and/or waste water”. Remarks 1 The mine water refers to the water which wells out from underground excavated for the purpose of digging minerals. 2 The waste water refers to the water which is discarded after having been used in t
9、he dressing plant, refinery and the like, and the wa- ter which flows out from the deposit of waste stones (including de- bris) and slag. 3 This Standard shall be also applicable to the water discharged from the disposal facilities of mine water and waste water. 2 Normative references The following
10、standards contain provisions which, through reference in this Standard, constitute provisions of this Standard. The most recent editions of the standards indicated below shall apply.

However, as to the testing methods of the fl
13、ame atomic absorption method, ICP atomic emission spec- trometry, ion selective electrode method, ion chromatography and dissolved oxy- gen, these shall be expressed by the concentration (mg/L) in the final solution. In the case where the quantitative ranges are different due to apparatus and measur
14、ing conditions, these matters have been appended. b) Analytical accuracy The analytical accuracy shall be indicated by the coef- ficient of variance() obtained in the repeated tests within the quantitative range of respective testing methods.

17、ric analysis specified in JIS K 8005 shall be used. In the preparation of reagents, the concentration indicated in the parenthe- ses after the name of solution means the approximate concentration. For example, sodium hydroxide solution (0.1 moVL) indicates that it is the con- centration of the sodiu
18、m hydroxide solution of approximately 0.1 mom. In addition, the concentration indicated before the name of solution means the accurate concentration. However, in general, it shall be indicated by a non- fractional numerical value, and otherwise, a factor shall be obtained. Further, if there are no s

In the case where a standard s
20、olution is to be prepared by diluting the standard solution, 10 ml or over shall be taken by a whole pipette. Naming of reagents should as closely as possible conform to the Nomencla- ture of Compounds established by the Chemical Society of Japan based on the IUPAC Nomenclature of Organic Chemistry
21、and the IUPAC Nomen- clature of Inorganic Chemistry. As to the treatments such as the waste liquids of the reagents, cares shall be sufficiently taken in accordance with the related laws, ordinances and rules. 4) 5) 6) e) Glass apparatus and the like The glass apparatus or glassware prescribed in JI
22、S R 3503 and JIS R 3505, unless otherwise specified, shall be used. However, in the case where particular apparatus is required, an example of it has been illustrated or explained in each item. Remarks : In the case where arsenic, zinc and the like are to be tested, care shall be taken to the elutio
23、n of these components from the borosili- cate glass. f) Measurement of absorbance (absorptiometry) If there is no remarks about the absorption cell, that of 10 mm in optical path length shall be used. g) Working curves (absorptiornetry, atomic absorption method and ICP atomic emission spectrometry)
24、In preparing the working curves, divide the quantitative range given in the testing method into 4 to 6 stages, and take the standard solution so as to coincide with these. The working curves shall be prepared only within the quantitative range. In the absorptiometry, the work- ing curves prepared in
25、 advance may be used.

26、564183 694 W 3 M 0202 : 1999 In the atomic absorption method and ICP atomic emission spectrometry, the newly prepared working curves shall be used at the time of test, and when the same metal is tested on a large quantity of sample, the confirmation of absor- bance or luminous intensity shall be car
27、ried out using a standard solution properly in the midst of the testing. h) Notes, remarks and tables The notes, remarks and tables are attached with a consecutive numbers in each clause. 4 Sample The sample mentioned in this testing methods refers to water sampled for carrying out each kind of test
28、, and it shall be representing the nature of water at the site where it has been sampled (hereafter referred to as “water at the site”). The sample shall be put in the sample container which has been cleansed in ad- vance and further with water at the site, filling it up, and carried into the test r
29、oom after tightly stoppering, and the test shall be carried out promptly. a) Sampling In the sampling, under sufficient understanding of the test object, considering the conditions of the mine water and/or waste water, namely the operation and seasonalhime functional matters, sufficient cares shall
30、be taken, so as to collect the samples representing water at the site and being in accor- dance with the test objects. In the case where there is the possibility of varia- tion in quality of water, the number of samplings shall be increased so as to recognize the actual state of the mine water and/o
31、r waste water correctly, as required. 1) Sampling spots The sampling spots shall be the places where the nec- essary conditions conforming to the test objects are to be satisfied. Example 1 Mine water Pit mouth and the like Example 2 Supernatant water and penetrant water of waste stones, slag deposi
32、ts and the like Water opening of each type Example 3 Various waste waters of refinery Water opening of each type Example 4 Processing facilities of mine water and waste water Front and rear of a processing facilities or immediately before flow- ing into a public water region 2) Sample vessels The sa
33、mple vessels used shall be the polyethylene bottles with a ground stopper or colorless borosilicate glass bottles with a ground stopper and the like. Avoid the use of the sample vessels with rubber, cork stopper and the like, in order to prevent the mingling of other substances and loss of each comp
34、onent from the sample. The sample vessels, which have been cleansed sufficiently in advance, shall be used after being washed 2 or 3 times with water at the site. Remarks 1 Depending on the kinds of the mine water and waste water, if insoluble matters and the like in the sample adhere to the wall of
35、 vessel, when the vessel is washed with water at the site, the vessels washed with water and dried shall be used.

37、. In addition, cares shall be taken for the possibility of elution of zinc, arsenic and the like from the glass bottles. 3) Sampling methods The sampling shall be so conducted as to represent the properties of water at the site. In sampling, the sampling vessels shall be used, and other water sam- p
38、ler shall be used for the special case. Depending on the water properties of the sample, the water sampler made of metal (bucket and other sampler made of metal) shall not be used. When the bucket made of metal can not be used, the bucket made of polyethylene, a water sampler with handle (dip- per)
39、and the like may be used. Before using the water sampler, it shall be sufficiently washed with water at the site in the same manner as the sample vessel. The ropes, strings and the like attached to the water sampler shall be sufficiently washed with water at the site so as to prevent the sample from
40、 being deteriorated. As to these general operations, refer to 4 of JIS K 0094. Remarks 2 The automatic water samplers consist of a system which col- lects a definite quantity of sample into separate vessels for a definite time or in accordance with an established condition, and a composite system wh
41、ich makes up a mixed sample by collecting the sample proportional to the flow rate continuously or intermittently into the same vessel, however, in using these systems, it is necessary to pay attention to the following points: a) Avoid the application to the measurements of the dissolved oxygen caus
42、ing errors on measured values due to the suc- tion collection of the sample, or the oil content or the like which is prohibited from transfering of the sample. b) At the time of the tests on easy deteriorating characteris- tics such as the biochemical oxygen demand (BOD) and chemical oxygen demand (
43、COD), the sample vessels shall be preserved in a low temperature equipment. 4) Handling of sample The sample shall be carried to the test room keep- ing its quality, and shall be tested promptly with sufficient care so as to prevent the sample from changing in quality as far as possible. Although th
44、e handling of samples differs depending on the respective test items, samples shall be treated as classified in the following. 4.1) Where metallic components are tested using total quantity compo- nent samples When carrying out the test requiring the respective total quantity(1) of the component to
45、be determined, the sample shall be left as sampled. However, if it is impossible to carry out the test immediately after the sampling, the samples to be used in the tests of copper, lead, zinc, cadmium, chromium, iron, manganese, arsenic, mercury, molybdenum, cal- cium, magnesium, and aluminium, imm
46、ediately after sampling, add with the rate of 10 ml of nitric acid(2) per L of sample water (in the case of strong Copyright Japanese Standards Association Provided by IHS under license with JSALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/13/2007 21:01:52 MDTNo reproductio

As to the sample to be used for the test of arsenic and
48、it does not include organic matter, nitrate and nitrite, the hydrochloric acid (for arsenic analysis) shall be used instead of nitric acid. Further, the samples to be used in the tests of iron (II) and chro- mium (VI) shall be tested as soon as possible without carrying out the treat- ment for prese
49、rvation. Where metallic components are tested using dissolved component samples When the test requiring the dissolved component only, the sample shall be filtrated by the filter paper type 5 C at the site(3) (the first 50 ml of the filtrate is discarded), and its filtrate shall be put in the sample ves- sel. However, in the case where the test i
