摘要:
酒中微量锌与饮酒人的健康有很大的关系。本文提出用阳极溶出伏安法直接测定酒中微量锌,探讨了酒中锌的阳极溶出行为及其测试的最佳条件,在pH=5-6的NH4Cl—HCl底溶中,使用铂基汞膜电极及大面积银汞膜参比电极,富集电位-1.3v,测量锌的溶出峰,Ep=-0.68v,波形良好,不需要分离和化学富集,方法简单,快速,线性范围为2-100ppb,酒中含锌25ppb的相对标准偏差为1.0%,灵敏度0.2ppb,回收率为99—107%之间。
Abstract:
A method of anodic stripping voitammety(ASV)was developed for the determination of trace zinc in the wine which related to the health of drinkers, This is a method of simple and quick, it is not necessary to separate and preconcentrate. The features of st
