摘要
目的建立饮用水中氯消毒副产物卤乙酸的测定方法。方法采用气相色谱法,微电子捕获检测器(如安捷伦6890型),色谱柱为DB-5,30m×0.25mm×0.25μm,改进了原方法的升温程序和预处理过程。结果色谱图分离效果好,线性关系良好(R2>0.999),检出限低。结论本法简单、安全、可行、易于推广。
Objective To establish a method for determination of haloacetic acids（HAAs） in water.Methods Gas Chromatograph,with a micro ECD（Agilent Model 6890）,GC column-DB-5,30-meter length,0.25-mm i.d.,0.25-μm film,the modification made to temperature program and sample procedure.Results The chromatogram shows well isolated peaks of HAAs,calibration curves of high linearity were obtained in all cases（R20：999）,the detection limits were low.Conclusion This method was simpler,safer,more feasible.
