| Abstract: | A novel solid-phase microextraction（SPME） fiber was prepared by coating carbon nanotube on a stainless steel wire,and was used for the determination of aniline in water by headspace-solid phase microextraction（HS-SPME） combined gas chromatography（GC）.The HS-SPME was optimized for the most important parameters such as extraction time and temperature,ionic strength and agitation.The method showed good linearity between 0.1 and 50 mg/L with regression coefficients ranging between 0.995 5 and 0.998 7.The detection limits of the developed method for water sample were below 0.074 mg/L for all analytes.This method has been applied to real samples and the recovery values in the range of 78%～112% for different aniline,the relative standard deviations were below 11.28%. |
