摘要
用消毒剂优氯净氧化降解甲基橙废水。考察了溶液pH、反应温度、反应时间、优氯净用量等因素对甲基橙废水脱色率的影响。结果表明:室温、溶液pH 5.0~8.0的条件下,1000 mL甲基橙含量为20 mg·L^(-1)的废水中加入80 mg优氯净,搅拌15 min,脱色率可达98%以上。
Sodium dichloroisocyanurate was used to decompose methyl orange through oxidative reactions.The effects of pH value,reaction temperature,reaction time and the dosage of sodium dichloroisocyanurate on the decolourization rate of methyl orange wastewater were investigated.The results showed that that decolourization rate reached 98%when optimum conditions were used:room temperature,stirring time 15 min,pH value 5.0~8.0,sodium dichloroisocyanurate dosage 80 mg,20 mg·L^(-1) methyl orange wastewater 1000 mL.
