An immunoaffinity chromatography column was developed to remove diazinon from water and soil samples. In this paper, two types of absorbent columns, the immunoaffinity chromatography column and the ENVI-Carb column, were compared. To accomplish this, each of these columns was used to treat water and soil samples that had been spiked with diazinon at concentrations of 2.5 or 5 ng/mL (or ng/g). High performance liquid chromatography was then used to analyze the treated samples. The ENVI-Carb column recovered 87.99%-95.95% of the diazinon from water and soil with CVs of 5.08%-8.06%. The recoveries observed when the immunoaffinity chromatography column was used were slightly lower (52.61%-81.58%); however, it effectively clean up the soil samples.
开发了一种免疫亲和色谱柱用于从水和土壤样品中去除二嗪农。本文比较了两种类型的吸附柱，即免疫亲和色谱柱和ENVI-Carb柱。为此，使用每种柱处理添加了浓度为2.5或5 ng/mL（或ng/g）二嗪农的水和土壤样品。然后使用高效液相色谱法分析处理后的样品。ENVI-Carb柱从水和土壤中回收了87.99%-95.95%的二嗪农，变异系数为5.08%-8.06%。使用免疫亲和色谱柱时观察到的回收率略低（52.61%-81.58%）；然而，它有效地净化了土壤样品。
