摘　　要：用离子色谱法测定氯化铵中的硫酸盐,线性范围广,线性范围分别为0.1～20.0mg/L.本法具有较好的精密度和准确度,加标回收率在91.1％～105.0％之间,相对标准偏差为0.93％.该法操作简单,干扰因素少,选择适当的样品浓度,可消除基体物质氯离子对硫酸盐的干扰,是测定氯化铵中硫酸盐快速、有效的方法.With ion chromatography for determination of sulfate in ammonium chloride, wide linear range, the linear range respectively 0.1- 20.0 mg/L has good precision and accuracy of this law, the standard addition recovery is between 91.1 %-105.0 %, relative standard deviation is 0.93 %. The operation is simple, less interference factors, select the appropriate sample concentration, can eliminate the interference of matrix material chloride with sulfate, the method is effective determination of sulfate in ammonium chloride.
