摘要
采用离子选择电极法测定蔗糖中铜的含量.方法简便、快速、准确.标准曲线线性范围1.00×10-6~1.00×10-4mol/L,平均回收率101.5%,RSD=2.4%(N=4).
Copper in sucrose was assayed by ion selective electrode.The method was simpe, rapid and accurate.The standard curve was linear in the range from 1.00×10 -6 ~1.00×10 -4 mol/L. The average recovery was 101.5%, RSD =2.4%( N =4).
