利用Triolein-半渗透膜采样技术测定淮河水中的有毒有机污染物

利用 Triolein 半渗透膜采样技术 ( Triolein SPMD)采集了淮河信阳、淮南断面水样 ,测定了采样器中多氯联苯、多环芳烃、取代苯等有毒有机污染物浓度。污染物在 SPMD酯中高浓度富集 ,使其定性和定量更加容易和准确。根据SPMD酯 水分配平衡理论 ,进一步估算得到目标污染物在水中的平均浓度。本研究证明 Triolein SPMD技术可用于水中多氯联苯、多环芳烃、取代苯等污染物的采集和定量分析 ,可在我国的优先污染物监测、控制工作中发挥作用。

Monitoring toxic and organic pollutants in the Huaihe River using Triolein SPMD

Triolein Semipermeable membrane device (Triolein SPMD) was used to monitor toxic and organic pollutants such as PCBs, PAHs, and Substituted Benzenes in the Huaihe River, at the sites of Xinyang and Huainan city, where organic pollution is very severe. High concentrations of pollutants in SPMDs, inferred that SPMDs could be used to qualify hydrophobic pollutants like PCBs, PAHs, and Substituted Benzenes and quantitate their concentrations in water. Average concentrations of pollutants we studied in the Huaihe River were extimated according to their concentrations in SPMD triolein, respectively.
