利用多孔高聚物浓缩提取水中痕量有机化合物,是国外近年来提出的一项新技术,可适用于水中多种痕量有机物。目前已广泛用于实验室研究和实际水样分析。最近几年国内对该项技术也有所注意。但大多处于实验室研究阶段,即对有机化合物的纯溶液进行吸附实验研究,实际应用的报道尚不多见。本工作对XAD-2树脂吸附水中ppb量级有机氯农药的条件进行了研究,并用实际水样分析将树脂吸附提取法与经典的溶剂萃取法进行了比较,结果基本一致。
The use of porous polymer concentrate extraction of trace organic compounds in water is a new technology proposed by foreign countries in recent years, which can be applied to a variety of trace organic compounds in water. Has been widely used in laboratory studies and actual water samples. In recent years, the domestic technology also pay attention. However, most of them are in the research stage of the laboratory, that is, the adsorption experiments on pure solutions of organic compounds are still rare. In this work, the conditions of adsorption of ppb organochlorine pesticides in water by XAD-2 resin were studied, and the results of the resin adsorption extraction method and the classical solvent extraction method were compared with the actual water sample analysis.
