摘要
Abstract
A high performance liquid chromatography for the analysis of residual monomers,2-acrylamido-2-methyl propane sulfonic acid(AMPS) and acrylamide(AM),in AM/AMPS copolymer was established.In order to reduce the viscosity of samples,the mixture of isopropanol and ethanol was used as the extractant to extract AMPS and AM from the aqueous solution of AM/AMPS copolymer.The effects of the wavelength and proportion of mobile phases on the separation were investigated to choose the optimal analysis conditions.The results show that the optimal conditions are as follow:chromatographic column ZORBAX SB-C18(4.0 mm×150 mm),volume ratio of methanol to water 85∶15 as the mobile phase,flow rate of the mobile phase 1.0 mL/min,UV absorption wavelength 220 nm,column temperature 27℃ and sample dosage 6 μL.The calibration curves of AMPS and AM were established.Their correlation coefficients were above 0.9995.The recoveries of the two components were in the range of 97.50％-100.62％ and the relative standard deviations were in the range of 0.435 7％-1.2981％.The method is accurate,rapid and sensitive.关键词
