Abstract：
 This invention relates to polar incretory interferent sampling testing method and its device in water environment. Dynamic absorbing capability of polystyrene divinyl benzene pyrrolidone absorbent to organic pollutants is used in this invention. Two pills of filter film that contain particle state absorbent between the two films are fixed by clamping collar to make it can steady stand in water body long time, water and compound can through the filter film, and other particle state matter are prevent entering the film and interfacing absorbing materials absorbing capability, so extraction and enrichment of polar organic pollutants in water is realized, then pollutants concentration is tested. This invention can realize time series concentration detect of water pollution. Comparing to traditional method, this invention can further estimate pollution level of water environment, and can be used to different water body, for example, fresh water, river water and sea water, and there is no need of extra power and inspecting, operation technique and equipment is simple.
