| 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 conditions 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-1, 2-propylene glycol in PAE were 0.01~0.1 mg/L and 1.0~10 mg/L， respectively， the correlation coefficients 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 pretreatment time and cost， and was suitable for the rapid determination of chloropropanol in PAE wet strength agent samples. |
