固相萃取-气相色谱质谱法测定地表水中硝基氯苯残留量

Determination of nitrochlorobenzene residues in surface water by solid phase extraction and gas chromatography-mass spectrometry

采用固相萃取-气相色谱质谱法测定地表水中硝基氯苯残留量,并通过萃取条件优化,选择HLB柱为固相萃取柱,正己烷:丙酮(V∶V,3∶2)溶液为洗脱剂。实验结果表明,该方法具有实用性强、操作简便快速、重复性好、灵敏度高、定性定量结果准确可靠等优点,可满足地表水中硝基氯苯类物质残留量的检测需要。

The residue of nitrochlorobenzene in surface water was determined by spe-gc-ms.the HLB column was selected as the solid phase extraction column and the n-hexane:acetone(V∶V,3∶2)solution as the eluant.The experimental results show that this method has the advantages of strong practicability,simple and fast operation,good repeatability,high sensitivity,accurate and reliable qualitative and quantitative results,and can meet the needs of the detection of nitrochlorobenzene residues in surface water.
