43、aw materials Trichloroisocyanuric acid is manufactured from isocyanuric acid (CNOH)3, sodium hydroxide (NaOH) and chlorine (Cl2). A.1.2 Manufacturing process Trichloroisocyanuric acid is produced by chlorination of trisodium cyanurate (Na3(NCO)3) using chlorine (Cl2). Trisodium cyanurate is obtained
44、 by the action of sodium hydroxide on isocyarunic acid. A.2 Use A.2.1 Function The product is used as disinfectant of swimming pool water. It is an indirect source of free chlorine (HOCl) when dissolved in water, via an organic carrier substance (cyanuric acid, C3N3O3H3): C3N3O3Cl3 + 3H2O C3N3O3H3 +
45、 3HOCl. (A.1) As the disinfectant (HOCl) is used up, more chlorine atoms are released from trichloroisocyanuric acid to form hypochlorous acid. This results in an enrichment of isocyanuric acid in the pool water, which cannot be removed by the water treatment process. Only dilution with fresh water
46、keeps the isocyanuric acid concentration at a satisfactory level. If the isocyanuric acid concentration becomes too high, unsatisfactory disinfection can result. The automatic amperometric monitoring of free chlorine residual is negatively affected by isocyanuric acid. A.2.2 Form in which it is used
47、 The product is used in tablet and granular form. A.2.3 Treatment dose Subject to national regulations, depending on the required free chlorine concentration in the pool water. A.2.4 Means of application The product is dissolved either directly or using a dissolution device; care should be taken whe
48、n used with liner or paint as bleaching can take place.

49、 of cyanuric acid and concentration; oxidation of iron, manganese and ammonium compounds; slight increase of “Kjeldahl“ nitrogen; slight increase in the chloride content; odour and colour removal; chlorination of organic compounds leading to formation of halogenated by-products (e.g. trihalomethanes). A.2.6 Removal of excess product Removal of excess product is achieved (dechlorination of excess product) by using an aqueous solution of sodium hyposu
