益阳市不同水体中苯系污染物的研究

Study of the BTEX Contaminants in Different Water Body from Yiyang City

了解益阳市的水体苯系物污染情况,为环保部门采取合适的环境保护措施提供依据。本研究优化了水样中苯系物的萃取方法,并用气相色谱仪检测益阳市不同水体中苯、甲苯、苯乙烯,邻二甲苯、间二甲苯、对二甲苯的含量,检出限均低于10μg/L,该方法在苯系物浓度为50-500μg/L间呈良好线性关系,RSD在4.2%以内,具有良好的重复性,采集的各水体中未检出苯系物。

A study about Learning the BTEX contamination in water of Yiyang City, take appropriate protection measures for the environmental protection sector basis. In this study, a method was optimized to extract BTEX contaminants in water samples, and detect the BTEX contaminants in different water body from Yiyang City by using gas chromatograph, includes Benzene, toluene, styrene, o-xylene, m-xylene, p-xylene. The method had a good linear relationship when the concentration of BTEX concentration was 50-500 μg / L, the limits of detection were bellow 10 μg / L, and the RSDs were less than 4.2%, had a good linear relationship. Each acquisition were not detected in water BTEX.
