作者研究了有机氯农药及共有关化合物在三种对高温稳定的混合相:OV-1/OV-17,OV-210/OV-17和OV-225/OV-17上的分离情况(OV-1为甲基硅酮,OV-17为甲苯基硅酮,OV-210为甲基三氟丙基硅酮,OV-225为甲苯基氰丙基硅酮)。试剂: 1.固定液——OV-1,OV-17和OV-210,OV-225;2.Chamelite CS——二甲基二氯硅烷处理的助滤剂(Celite 545),80～100目,酸洗。柱填料的制备和柱的老化: 按每种固定液的重量百分数,分别秤取固定液,溶于400～500毫升溶剂中,加入担体,在
The authors investigated the isolation of organochlorine pesticides and their related compounds on three high temperature stable mixed phases: OV-1 / OV-17, OV-210 / OV-17 and OV- 225 / OV- 1 is methyl silicone, OV-17 is tolyl silicone, OV-210 is methyl trifluoropropyl silicone, and OV-225 is tolyl cyanopropyl silicone). Reagents: 1. Fixing solutions - OV-1, OV-17 and OV-210, OV-225; 2. Chamelite CS - Dimethyldichlorosilane-treated filter aid (Celite 545) , Pickling. Preparation of column packing and column aging: according to the weight percentage of each fixing solution were weighed fixed solution, dissolved in 400 to 500 ml of solvent, added to the carrier, at
