摘要：

The anodic stripping voltammetric characteristics of lead at a mercury ultramicroelectrode were investigated. A procedure for the digestion of 1 mg human hair with nitric and perchloric acids and an anodic stripping voltammetric technique for determining trace lead in 5-mu-l of solution are described. The relative standard deviation of the method is 4.1% for 1 X 10(-7) Mol l-1 Pb2+ at a mercury ultramicroelectrode with a radius of 5-mu-m.
