本文采用Florisil Sep-PaK柱分离提纯富集的有机氯农药,用GC法测定蜂蜜中艾氏剂等8种有机氯农药的含量。通过对分离提纯方法的改进,使用Florisil Sep-PaK柱,大大地简化了分离提纯步骤。改进后的方法,不需要复杂的分离提纯过程,分析速度快,回收率高,重现性好,所分析的8种有机氯农药的检测限在0.48～2.78μg/L之间。实验步骤将25g样品溶于50ml经己烷处理过的蒸馏水中,用50ml己烷萃取。然后
In this paper, Florisil Sep-PaK column separation and purification of enriched organochlorine pesticides, GC determination of aldrin and other 8 kinds of organochlorine pesticides in honey content. Through the improvement of separation and purification methods, using Florisil Sep-PaK column, greatly simplifies the separation and purification steps. The improved method does not require complex separation and purification process, the analysis speed is high, the recovery rate is high, and the reproducibility is good. The detection limits of the eight organochlorine pesticides analyzed are between 0.48 and 2.78 μg / L. Experimental Procedures 25 g of sample was dissolved in 50 ml of hexane-treated distilled water and extracted with 50 ml of hexane. then
