In the air samples ,di(2-ethylhexy) phthalate,di-n-butyl phthalate and dioctyl phthalate were included,while diethyl phthalate,di(2-ethylhexy) phthalate,dipropyl phthalate,butyl benzyl phthalate,dioctyl phtha...

大气环境样品中邻苯二甲酸酯类化合物的预处理主要采用的是索氏提取、溶液提取和填充柱分离；水环境样品中采用的前处理技术较多，但大多数都是萃取技术；底质和生物试样目前用的较多是微波萃取、超声波萃取和索氏提取。

The serum selenium is first digested by microwave treatment and then chemically purified before analysis by using sulphydryl cotton. The optimum conditions were found to b as follows:(1) The sulphydryl cotton column is prewashed with 5 mol/L hydrochloric acid;(2) Se is desorbed by adding 1 mL of concentrated nitric acid and (3) the optimum amount of sulphydryl cotton is 0.14 g. This preconcentration step is required in order to remove matrix-interfering elements, such as Na, Mg, K and Ca.

采用微波消解－巯基棉分离对人血清样品进行前处理，通过对巯基棉分离血清中硒的条件优化，结果表明，柱条件为5mol/L HCl、解脱Se条件为1mL重蒸HNO3、巯基棉最佳用量为0.14g时，能够有效分离出人血清样品中的Na、Mg、K、Ca等碱金属和碱土金属，同时硒的回收率最高，达到92%以上。
