【摘要】 目的建立顶空气相色谱法测定泳池水中三氯甲烷的含量。方法通过一系列GC参数的优化实验,选择最佳的顶空条件和色谱参数。结果三氯甲烷在1.00μg/L～200μg/L范围内呈良好的线性关系(r=0.999 1);平均回收率为92.3%～95.5%,RSD为2.2%～4.6%(n=6);最低检出限为0.10μg/L。结论该方法灵敏、简单、准确,可用于测定泳池水中三氯甲烷的含量。更多还原

【Abstract】 Objective To determine the content of chloroform in swimming pool water by Headspace Gas Chromatography.Methods By carrying out a set of experiments with GC parameters to select optimal headspace condition as well as chromatographic parameter.Results The content of chloroform showed considerable linear correlation(r=0.999 1) within 1.0-200.0 μg/L;the average recovery rate of chloroform was within 92.3%-95.5% with RSD ranging from 2.2% to 4.6%(n=6);the lowest detection limit was 0.10 μg/ml.Conclusion The method is simple,sensitive,yet accurate to determinate the chloroform in swimming pool water.更多还原
