A simple, precise and accurate analysis for lead in blood and tissue was developed using spectrophotometry after extraction with HCl, H 3 PO 4 , KI and methyl isobutyl ketone. The results were similar to those obtained by anodic stripping voltammetry. The method is simple, requires only four reagents, does not need pH adjustment for lead extraction, saves time and is suitable for analyzing a large number of specimens.
