摘要
Abstract
A method for simultaneous determination of anions and cations in mineral water by dual channel ion chromatography was established/The anion channel selected SH-Anion-013 anion column as the separation column, 3.6 mmol/L Na2CO3 was used as the eluent and the flow rate was 0.7 mL/min.The detection mode was suppressed conductivity .The cation channel selected SH-Cation-012 cation column as the separation column, 3.0 mmol/L methane sulfonic acid was used as the eiuent and the flow rate was 1.0mL/min, The detection mode was direct conductivity. It showed that the method had broad linearity range,good comelation(R>0.999),high precision(RSD≤235 %) and the average recoveries of actual samples were 92.5% ~103.8%, It can entirely satisfy the determination requirement and can be applied to analyze anions and cations in mineral water.关键词
