Simultaneous determination of six aniline compounds in surface water by GC-MS
A method for simultaneous determination of aniline,2-chloroaniline,3-chloroaniline,4-chloroaniline,4-bro moaniline and 3-nitroaniline residues in surface water by gas chromatography-mass spectrometry was established by using solid phase extraction column as the pretreatment for enrichment of water samples.The linearity of the six aniline compounds was good in the concentration range of 3.00~200μg·L-1.The recoveries were 87.1%~104.3%and the relative standard deviations were 1.9%~4.2%.The method has the advantages of simple operation,high sensitivity and accuracy,low detection limit,and meets the requirements for the analysis of aniline residues in water.
