A simple, rapid and accurate complexometric method for the determination of palladium in the presence of other metal ions is described, based on the selective masking ability of 2-mercaptoethylamine (MEA) towards Pd(II). Palladium(II) along with other associated metal ions present in a given sample solution is first complexed with an excess of EDTA and the surplus EDTA is titrated with zinc sulphate solution at pH 5-6 (acetic acid-sodium acetate buffer) using xylenol as indicator.
