BS EN 15032:2006+A1:2008EN 15032:2006+A1:2008 (E) 9 Annex A (informative) General information on trichloroisocyanuric acid A.1 Origin A.1.1 Raw materials Trichloroisocyanuric acid is manufactured from isoc

40、yanuric 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 by the action of sodium hydroxide on isocyarunic acid. A.2 Use

41、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+ 3HOCl. (A.1) As the disinfectant (HOCl) is used up, more chlorine

42、 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 keeps the isocyanuric acid concentration at a satisfactory level.

43、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 The product is used in tablet and granular form. A.2.3 Treatment

44、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 when used with liner or paint as bleaching can take place. BS EN 1503

45、2:2006+A1:2008EN 15032:2006+A1:2008 (E) 10 A.2.5 Secondary effects The secondary effects include the following: build-up 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

46、 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 hyposulfite (thiosulfate), sodium

47、 sulfite or sodium hydrogenosulfite. Passing through activated carbon is also effective.
