44、BS EN 15072:2013EN 15072:2013 (E) 12 Annex A (informative) General information on sodium dichloroisocyanurate, anhydrous A.1 Origin A.1.1 Raw materials Sodium dichloroisocyanurate, anhydrous is manufactured from isocyanuric acid (CNOH)3, sodium hydroxide (NaOH) and chlorine (Cl2). A.1.2 Manufacturin
45、g process Sodium dichloroisocyanurate, anhydrous is produced by chlorination of disodium cyanurate (Na2H(NCO)3) using chlorine (Cl2) and neutralisation with sodium hydroxide (NaOH). Disodium cyanurate is obtained by action of sodium hydroxide on isocyanuric acid. A.2 Use A.2.1 Function The product i
46、s used as a disinfectant of swimming pool water. It is an indirect source of free chlorine (HOCl) when dissolved in water via an organic carrier substance (sodium cyanurate, C3N3O3H2Na): C3N3O3Cl2Na + 2H2O - C3N3O3H2Na + 2HOCl (A.1) As the disinfectant (HOCl) is used up, more chlorine atoms are rele
47、ased from “sodium dichloroisocyanurate, anhydrous“ to form hypochlorous acid. This results in an enrichment of sodium isocyanurate in the pool water which cannot be removed by the water treatment process. Only dilution with fresh water keeps the sodium isocyanurate concentration at a satisfactory le
48、vel. If the sodium isocyanurate concentration becomes too high, unsatisfactory disinfection can result. The automatic amperometric monitoring of free chlorine residual is negatively affected by sodium isocyanurate. A.2.2 Form in which it is used The product is used in tablet and granular form. A.2.3
49、 Treatment dose The treatment dose is subject to national regulations, depending on the required free chlorine concentration in the pool water In order to have 2,5 mg/l free chlorine concentration, one should add 3,97g/m3of sodium dichloroisocyanurate, anhydrous. A.2.4 Means of application The product is dissolved either directly or using a dissolution device.
