| 摘 要： | 建立了抑制电导检测离子色谱法同时测定甲基亚磺酸钠中氯离子和硫酸根离子的方法.Cl-和SO42-分别在0.2～25 mg/L(r=0.9999)和0.1～10 mg/L(r=0.999 6)浓度范围内线性关系良好,甲基亚磺酸钠中Cl-和SO42-的方法平均回收率分别为102％(RSD为0.36％)和101％(RSD为0.61％),检出限分别为0.011和0.014 mg/L.该方法具有线性范围良好、检出限低、操作简便、可靠等优点,可作为甲基亚磺酸钠中的Cl-和SO42-质量控制方法.

| Abstract: | To establish a method for the simultaneous determination of Cl-and SO42-in sodium methanesulfinate by ion chromatography with suppression conductivity detector.The calibration curve was linear in the range of 0.2 ～25 mg/L(r =0.999 9) and 0.1～10 mg/L(r=0.9996) for Cl-and SO42-rspectively.The mean recovery of Cl-and SO42-were 102％(RSD of 0.36％) and 101％ (RSD of 0.61％) respectively.Detection limits for Cl-and SO42-were 0.011 and 0.014 mg/L respectively.This method has the benefits of good linear range,low detection limit,easy operation and reliable.It can be used as the quality control method of Cl-and SO42-in sodium methanesulfinate. |
