摘要
本文研究了测定酒中痕量铅的微分电位溶出法。该法检测下限为0.1ug·L^(-1)pb,在0～10ug·L^(-1)浓度范围内有良好线性关系,用于酒中痕量铅的直接测定,其相对标准偏差小于4.5%,回收率为98.5～103%,结果令人满意。
This paper studied the determination of trace lead in wines by derivative potential stripping. The calibration curve is liner from o up to 10ug/L. The r. s. d. is 4. 5%. The rate of recovery is 98. 5～103% Results of the deterimination of trace lead in wines are satisfactory.
