Determination of sultones in α-olefin sulfonate by high performance liquid chromatography
摘要
Abstract
A method for the determination of sultones in α-olefin sulfonate by high performance liquid chromatography(HPLC)was developed.This method was used to monitor the risk of 4 batches of α-olefin sulfonate samples on the market.The samples were dissolved in water and ethanol,and then extracted with petroleum ether.The extracts were dissolved in the mixed solution of n-hexane and isopropyl alcohol,and the equal degree elution was performed using n-hexane and isopropyl alcohol as the mobile phase by high performance liquid chromatography.The volume ratio of n-hexane to isopropyl alcohol was 8∶2.The extracts were separated by Inertsil CN-3 column(250 mm×4.6 mm×5µm)at the flow rate of 2.0 mL/min.The injection volume was 20µL and the column temperature was 25℃.The detector was the evaporative light scattering detector.The temperature of the drift tube was 80℃,and the flow rate of carrier gas was 2.0 L/min.The quantitative method was external standard method.The results show that the mass concentration of sultones in the range of 80-200 μg/mL shows a good linear relationship,and the detection limit is 5.25 μg/mL with the correlation coefficient greater than 0.989.The relative standard deviation is 1.01%(n=6).The recoveries of sultones are 102.82%-108.24%.The method has good separation effect,good linear relationship,simple operation,high sensitivity,and good accuracy and repeatability.The method can quickly and accurately measure the residual amount of sultones in α-olefin sulfonate.关键词
