| 摘 要： | 天然水体中的痕量持久性有机污染物(POPs)的定量分析通常需要采集大体积水样.针对大体积水样在过滤和吸附富集过程中滤膜易堵塞且耗时费力的缺点,研制了一种固液分离过滤-吸附富集联动装置.该装置主要由粗过滤器、离心分离屏、倒置微孔过滤器、固相吸附柱、流速控制阀和真空泵组成.与传统的滤膜过滤方式相比,其过滤效率提高了约1.5...

| Abstract: | A high-volume water sampling is a necessary means to quantify trace persistent organic pollutants(POPs) in natural water.However,the filter is so easily blocked that the filtration work can take a long time during the filtration of high-volume water.As for the disadvantage,a filtration-adsorption linkage water sampling equipment was developed.It was mainly composed of preliminary filter,centrifugal separation shield,upside-down membrane filter,solid-phase adsorption column,flow rate control valve,and vacuum... |
