- Abstract:
- A sodium carbonate-sodium bicarbonate system ion chromatography method was established for detection of acrylic acid in groundwater, surface water, domestic sewage, industrial wastewater and other water samples. Sample collection conditions, sample pretreatment conditions, chromatographic conditions and preservation conditions of standard solution were optimized respectively. The water samples were purified by IC-Na column, IC-Ag column, IC-Ba column and C18 column, and acrylic acid was separated by sodium carbonate-sodium bicarbonate eluent and AS22 chromatographic column and finally determined by a conductivity detector. The detection limit was 0.008 mg/L, and the correlation coefficient of the standard curve was 0.999 9. The recovery rates of different types of actual water samples were 92.0%-115%, and the relative standard deviations of six parallel determinations were 1.2%-6.5%, indicating that the method had the advantages of low detection limit, good linearity of standard curve, high accuracy, good precision, simple steps, high analysis efficiency and low experimental cost. The method can adapt to acrylic acid determination in different types of water samples and has a good application prospect in the field of environmental monitoring.
