摘要
主要考察了氯、二氧化氯和二氧化氯/氯(二氧化氯占混合溶液的质量分数为50%,90%)这3种消毒剂与苯酚等9种THMS前驱物的反应,并对这3种消毒剂在前驱物含量、反应pH值、反应时间和反应温度等条件下生成的氯仿量进行了比较。研究结果表明:二氧化氯消毒剂与THMS前驱物反应几乎不生成氯仿,而液氯却生成大量的氯仿,二氧化氯占50%的混合消毒剂仍然有氯仿生成,但是二氧化氯占90%的混合消毒剂氯仿生成量大大减少。
The paper compares the reaction of disinfectants of Cl, ClO2 and ClO2/Cl to 9 kinds THMs prodrome such as phenol , including volume from disinfectants on their prodrome contents, reaction pH values, reaction time, and reaction temperature. The results show that no CHCl3 produce is found from ClO2 and THMs prodrome, but more CHCl3 produce from Cl2. There＇s still some CHCl3 produce from 50 % ClO2 disinfectant, but much less CHCl3 produce from 90 % ClO2 disinfectant.
