【摘要】 微分电位溶出法测定白酒中的铅,样品不经处理可直接测定,且不受酒精度的影响,通过多次实验探索得平均回收率为:99.24%,标准差 S∶0.207,变异系数 Cv∶3.59%。这表明用电位溶出法测酒中的铅稳定性,重现性都较好,且方法简便,快速,灵敏度高,检出限达(0.5PPb)。更多还原

【Abstract】 Detection of lead in wine using DPSA was reported to be advantageous in that the samples might be directly tested without Previous treatment and were not affected by the density of alcohol.Repeated experiments showed that the average rate of recovery was 99.24%,the standard deviation vas 0.207,and the coefficient of variation was 3.5%,It vas indicated that this meth- od was satisfactory in stability and reappearance and was handy and quick with high sensitivity and an imspected volume of 0.5pph.更多还原
