Development andPreliminaryApplication of A Time-series Passive Sampler for Monitoring of Pollutants in Aquatic Environment Based on Osmotic Pump and Liquid Phase Microextraction

水环境污染物的时间序列数据是其时空分布、通量、迁移转化研究和环境风险评价的基础。样品采集是获取监测数据的重要步骤，但现有的采样技术难以用于获取时间序列监测数据。有鉴于此，本论文将渗透泵（osmoticpump，OP）和液相微萃取（liquidphasemicroextraction，LPME）相结合，研制了一种以OP为动力、以LPME为采样手段的新型被动采样器，并尝试将其应用于水体中污染物的时间序列浓度监测。主要的研究内容和结果如下： （1）将OP与LPME联用，研制了可获取水环境中污染物的时间序列浓度数据的OP-LPME采样器。该采样器包含6个部件，分别为1个OP、1个萃取溶剂储存盘管、1...The studies of the spatial and temporal distribution, flux, transport, transformation, and environmental risk assessment of pollutants in aquatic environment depend mainly on the time-series monitoring data of the pollutants. Sample collection is the key step for environmental monitoring. However, it is difficult to obtained time-series data when the traditional sampling technique is applied.
