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.
