硫酸钙中氯离子的测方法

The Determination Method of Chloride Ion in the Calcium Sulfate

建立了氯离子选择性电极对硫酸钙中氯离子含量的测定方法,建立工作曲线进行定量,通过精密度实验、加标回收率测定及实际样品检测验证方法简单、快速、准确,为饲料级硫酸钙的标准建立提供了理论依据。

Established a method for the determination of chloride ion in the calcium sulfate by using ion selective electrode, the working curve was bulided for quantified, the precision and recoveries experiments proved that the method is simple, rapid, and accurate, the method is suitable for the determination of fchloride ion in the calcium sulfate .The established method provide theoretical basis for national standard of feed grade calcium sulphate.
