Determination of lead in paint by differential-pulse anodic-stripping voltammetry

P. C. Lai  and  K. W. Fung  

Abstract

A procedure for the determination of lead in paints by differential-pulse anodic-stripping voltammetry is presented. Only a few milligrams of sample are required for the analysis. Dry ashing with sodium carbonate as the flux has been found to be a simple and effective method for the destruction of the organic matrix. Samples of the dried paint of small particle size should be used and the sample solution is adjusted to pH 4.0–4.6 with a buffer solution before analysis. Loss of lead by retention in a porcelain crucible is significant in analysis for trace levels of lead and a platinum crucible is recommended as the container in the ashing process. The inexpensive porcelain crucible can only be used if the lead content is of the order of 10–1 g.
