| 摘 要： | 首次对有机改进剂在液-液萃取、固相萃取预处理中的影响进行了系统研究。对比有机改进剂在水中有机氯液液萃取及固相萃取的萃取效果,结果表明:固相萃取前处理水样中添加一定量有机改进剂,可提高水中有机氯的回收率;而液液萃取前处理水样中不加有机改进剂,回收率较高。对不同有机改进剂及其用量在水中有机氯固相萃取的影响进行了研究,结果表明,甲醇效果较好,当每200 mL水样添加2.0 mL甲醇时回收率最高。考察了优化条件下分析方法的精密度和重现性,结果表明该方法稳定、可靠、重现性好。

| Abstract: | A systematic study was carried out for the first time on the impact of the organic modifier on the pre-processing of liquid-liquid extraction(LLE) and solid-phase extraction(SPE),and the extraction effects of LLE and SPE when using the organic modifier for the organic chlorine in water samples were compared.The results show that the rate of recovery of the organic chlorine by SPE in pre-processed water samples can be increased by adding a certain amount of organic modifier,and the rate of recovery of the or... |
