Abstract
Abstract The efficiency of solvent extraction of lead and cadmium for atomic absorption spectrophotometry was investigated. Quantitative extraction from an aqueous solution into methyl isobutyl ketone was possible, using sodium diethyl dithiocarbamate in the pH range of 5.5—8.5 for Cd and 5.5—7.5 for Pb. A 4-fold concentration from aqueous to organic solvent allowed accurate measurement (error <± 10%) of concentrations <0.02 μg Pb/ml and <0.05 μg Cd/ ml. Detection limits of 0.01 μg Pb/ml and 0.0005 fig Cd/ml were established.
