Determination of Distearyl Dimethyl Ammonium Chloride in Dyeing and Finishing Textile Agents by Ultrasound-assisted Extraction/LC -MS/MS
摘要
Abstract
An analytical method was established for the determination of distearyl dimethyl ammonium chloride( DSDMAC) in dyeing and finishing textile agents by ultrasound-assisted extraction combined with liquid chromatography - tandem mass spectrometry ( LC - MS/MS). The sample was extracted with methanol by ultrasound-assisted extraction. The extract was filtered and then detected by LC -MS/MS with electro-spray ionization source. The confirmation ion pairs were m/z 550. 5/298. 3 , 522. 5/298. 3 , 522. 5/270. 3 , 494. 5/270. 3 , and the quantification ion pairs were m/z 550. 5/ 298. 3 , 522. 5/298. 3 , 494. 5/270. 3. The calibration curve was linear for DSDMAC in the range of 0. 02 - 1. 0 mg/L with correlation coefficient of 0. 998 5. The limit of quantitation was 20 mg/kg. The recoveries of DSDMAC at the spiked range of 100 -500 mg/kg were between 86% and 96% , with relative standard deviations ( RSDs) of 3. 2% - 5. 4% . The experimental results indicated that the method was rapid, sensitive and accurate, and could meet the correlative requirements for determination of DSDMAC in dyeing and finishing textile agents.关键词
