Abstract

A new kinetic-spectrophotometric method for the determination of trace amount of palladium has been proposed. It is based on the palladium catalysed discoloring reaction of malachite green reduced by sodium hypophosphite in phosphoric acid buffer solution (pH = 2.0). The linear range of determination of palladium is 0-10 microgram.L-1, the detection limit is 9.78 x 10(-11) g.mL-1. The method has been used for the determination of palladium in some catalyst with satisfactory results. The mechanism of the reaction has also been discussed.
