Abstract
A rapid determination method of 1,3-dichloro-2-propyl alcohol and 3-chloro-1,2-proplylene glycol in polyamide-epichl-orohydrin(PAE)wet strength agents was developed by headspace solid phase microextraction-gas chromatography mass spectrometry.The optimized conditions were that using Divinylbenzene/Carbon Wide Range/Polydimethylsiloxane(DVB-CWR-PDMS)extraction head,under the condi-tions of sampling volume 2 mL at extraction temperature of 60 ℃ with extraction time for 30 min,heater speed of 300 r/min,analytical time of 2 min and NaCl addition amount of 1.2 g,the wet strength agent chloropropanol was extracted.DB-WAX column(30 m×0.25 mm× 0.25 μm)was separated and detected by ion monitoring mode selected by mass spectrometry,and quantified by external standard method.The linear ranges of 1,3-dichloro-2-propyl alcohol and 3-chloro-l,2-propylene glycol in PAE were 0.01～0.1 mg/L and 1.0～10 mg/L,re-spectively,the correlation coeficients were greater than 0.999,the recoveries were 95％～110％and 96％～113％,and the detection limits were 0.0001 mg/L and 0.1 mg/L,respectively.The method was simple,accurate,low detection limit,without derivatives,greatly reduced the pre-treatment time and cost,and was suitable for the rapid determination of chloropropanol in PAE wet strength agent samples.关键词
