Abstract: Decrease in available chlorine of sodium dichloroisocyanurate and its influence on the main chemical composition,toxicity to juvenile abalone(\%Haliotis discus\% hainai)and bactericidal properties were examined The results showed that the decrease rate of available chlorine in seawater abided by available chlorine time relationship: C=at b (a,b>0) Chlorine had good popularity for water purification,it could remove ammonia, nitrogen and nitrite nitrogen and decrease chemical oxygen demand When pH is 8 01, 24,48,72 h and 96h, medial lethal concentration of sodium dichloroisocyanurate to juvenile abalone were 5 75,2 90,2 00 and 1 71 mg/L, 0 5,2 h's were 52 72 and 22 80 mg/L TRC pH was highly correlated with toxicity Bacteria were highly sensitive to chlorine When exposure times were 1 h,4 h and 12 h the lowest total residual chlorine concentrations to distroy above 90% of bacteria were 5 52,3 79 and 1 36 mg/L TRC respectively 10 mg/L available chlorine concentration is proposed to disinfect alone
