| 摘 要： | 目的：探讨饮用水在氯化消毒过程中腐殖酸与生成卤乙酸之间的关系。方法：以柱前衍生-气相色谱法为检测手段。研究氯化条件对卤乙酸生成量的影响。结果：卤乙酸的生成量随温度升高、腐殖酸浓度增加、氯化剂用量增大和pH值降低而增加。结论：腐殖酸是饮用水氯化消毒副产物的重要前体物质。适当控制氯化条件，可减少消毒过程中卤乙酸的产生。

| Abstract: | Objective:To investigate the relationship between humic acid and chloroacetic acid in the process of chlorination disinfection for drinking water.Methods:The chloroacetic acid was quantitated by SPE-GC-ECD.Certain parameters were examined by one-factor-at-a-time experiment and the effect on the yield of chloroacetic acid was studied.Results:Within the tested domain,the yield of chloroacetic acid was increased with the rise of the temperature,humic acid,chlorine dose and the decrease of pH value.Conclusion:The humic acid is an important precursor substance of disinfection by products.The content of chloroacetic acid could be reduced through optimized condition of chlorination disinfection for drinking water. |
