| 摘 要： | 采用淋洗液发生器-抑制电导检测法,同时分离和检测16种无机阴离子和低分子量有机酸,建立了用亲水性阴离子交换分离柱,KOH为淋洗液等浓度泵作梯度淋洗的离子色谱分离方法. 该方法具有良好的重现性、线性关系. 除马来酸外,所有被测离子的检测限都在0.16 mg/L以下. 方法用于测定4种酒样品的分析,结果满意.样品测定的回收率在93.52%到116.08%之间,除富马酸外其它RSD都小于3.8%.

| Abstract: | A new method for simultaneous determination of ,sixteen organic acids and inorganic anions by using eluent generator suppressed conductivity detection ion chromatography was described. By using hydrophilic anion exchanged column and gradient eluent of KOH,good repeatability , linear relationship, and very low detect limits were obtained. Detection limits of inorganic anions and organic acids were under 0.15 mg/L. For the determination of organic acids and inorganic anions in four kinds of wine,the resuh was satisfactory, the rate of recovery was between 93.52% to 116.08%. |
