摘要:
针对地下水、地表水、生活污水及工业废水等不同类型水样中丙烯酸含量的监测，建立了一种碳酸钠-碳酸氢钠体系离子色谱测定方法。分别优化了采样条件、样品前处理条件、色谱条件以及标准溶液保存条件。利用IC-Na柱、IC-Ag柱、IC-Ba柱和C18柱净化水样，通过碳酸钠-碳酸氢钠淋洗液及AS22型色谱柱分离丙烯酸，以电导检测器测定。检出限为0.008 mg/L；标准曲线线性相关系数r为0.999 9；测定不同类型实际水样的加标回收率在92.0%～115%之间；6次平行测定相对标准偏差在1.2%～6.5%之间。该方法具有检出限低、标准曲线线性好、准确度高、精密度好、步骤简单、分析效率高、实验成本低等优点,能够适应不同类型复杂基质水样中丙烯酸的测定，在环境监测领域具有良好的应用前景。
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.
