Monothiodibenzoylmethane (HSDBM) was used for the quantitative extraction of palladium. It was extracted at pH 3.5–6.5, with 0.001 M HSDBM in benzene, as an orange-red colored complex and measured spectrophotometrically at 470 nm. Beer's law was valid in the concentration range of 0.6 to 3.6 μg of palladium per ml. The complex was stable for at least 144 h. Ten milliliters of 0.001 M HSDBM in benzene was adequate for quantitative extraction of palladium. The optimum period of equilibration was 10 min. It was possible to extract palladium in the presence of a large number of elements.
