A capillary zone electrophoresis (CZE) system for determining haloacetic acids in water was optimized with indirect photometric detection. Two different carrier electrolytes, potassium hydrogenphthalate and sodium 2,6-naphthalenedicarboxylate, were evaluated in terms of sensitivity and two different electroosmotic flow modifiers, tetradecyltrimethylammonium bromide and hexadecyltrimethylammonium bromide, were tested. Parameters such as electrolyte concentration and pH, and the concentration of the electroosmotic flow modifiers, which affect the CZE separations, were investigated. The method was used to determine haloacetic acids in chlorine tap water using the liquid-liquid extraction process.
采用间接光度检测法对用于测定水中卤乙酸的毛细管区带电泳（CZE）系统进行了优化。针对邻苯二甲酸氢钾和2,6-萘二甲酸钠这两种不同的载体电解质，从灵敏度方面进行了评估，并测试了溴化十四烷基三甲基铵和溴化十六烷基三甲基铵这两种不同的电渗流改性剂。研究了诸如电解质浓度、pH值以及电渗流改性剂浓度等影响CZE分离的参数。该方法通过液-液萃取过程用于测定氯自来水中的卤乙酸。
