沉积物中邻苯二甲酸二甲酯类的GC/MS测定

Detemination of Dimethyl(o-) phthalate in the Sediment by GC/MS

采用快速压力溶剂萃取仪(ASE)提取,弗罗里柱净化,气相色谱-质谱联用仪(GC/MS)对沉积物中邻苯二甲酸酯类化合物进行定性、定量分析。实验过程中采用铬酸洗液对实验器皿进行清洗,有效防止环境中邻苯二甲酸酯类物质对样品的污染。

The kind of compounds of dimethyl （ o - ） phthalate is determined quantificationally by extracting with ASE and GC/MS. All the vessels are cleaned by chromic acid lotion to avoid the dimethyl （o - ） phthalate in the environment to pollute the samples.
