摘要
建立了固相萃取、毛细管气相色谱-电子捕获检测、内标标准曲线法定量分析地表水中十三种氯苯、硝基氯苯和硝基苯类化合物的方法.该法对这些化合物的平均回收率在62%-101%之间,变异系数在3%-27%之间,方法最小检测浓度在0.01-1.31μg·1-1之间.应用本方法对太湖水中的氯代芳烃和硝基取代芳烃化合物进行了三次采样分析,定量重现性较好.
A method for the determination of chlorobenzenes, nitrobenzenes, chloronitrobenzenes in water has been established by solid - phase extraction, capillary gas chromatography with electron capture detector. The quantity fixed by inner standard curve method. The average recovery was between 62% and 101%. The relative standard deviation ranged from 3% to 27% . The minimal detection concentration was between 0.01μg·1-1 and 1.31μg·1-1. The content of 13 chloronitrobenzenes in Taihu lake water in three different times by the method was analyzed, the quantitative result recurred well.
