Abstract

The invention relates to a novel sampling system for organic pollutants in a water body, which comprises a filtering device, the main body of the filtering device is a syringe-shaped filtering pipe, or the upper part of the filtering device is a funnel-shaped syringe-shaped filtering pipe, and the bottom of the filtering pipe is provided with a filtering material; a sampling device, a main body of the sampling device is a pipe body, at least one end of the pipe body is provided with an opening, the opening is matched with a sealing cover, and the sampling device is filled with an adsorption material; the outer diameter of the opening formed in the sampling device tube body is the same as the diameter of the opening of the syringe-shaped filter tube of the filter device or the opening of the syringe-shaped filter tube with the funnel-shaped upper part; the adsorption material is a mixed weak anion reverse-phase adsorbent. The device is divided into a sampling device and a filtering device, so that the pretreatment of an organic pollutant sample is divided into two space and time separation links of sampling adsorption and filtering. The adsorption material can be used for adsorbing a target compound in a water body and then can settle into a filtering sand core in the filtering device only under the action of gravity.

Description

technical field [0001] The invention belongs to the technical field of water body pollutant analysis, in particular to a sampling device and a use method for measuring organic pollutants in a water environment. Background technique [0002] Water environment is an important environmental medium, and monitoring organic pollutants in water plays an important role in evaluating aquatic ecosystems and water quality security. Therefore, water sampling technology is very important. The detection and analysis of organic pollutants in water is mainly divided into three steps: sample collection, sample pretreatment and instrumental analysis. The current general method for the detection of organic pollutants in water samples is that researchers collect water samples in the field and send the water samples to the laboratory before pre-processing the samples. At present, the relatively mature method in the laboratory is to simply filter the water sample, and then enrich the filtered s...
