2-MERCAPTOETHYLAMINE AS A MASKING AGENT FOR THE COMPLEXOMETRIC DETERMINATION OF PALLADIUM(II) IN CATALYSTS, ALLOYS AND COMPLEXES

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...

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 acétate buffer) using xylenol as indicator. A known excess of 0.2% aqueous solution of MEA is then added to displace EDTA from Pd(II)-EDTA complex and swirled well. The released EDTA is again titrated with zinc sulphate solution as before. The method works well in the range 2-20 mg of palladium(II) with the relative error ± 0.27 and the relative standard deviation < 0.35%. The effect of the presence of various diverse ions on the accuracy of the results has been studied. The method has been satisfactorily applied for the determination of palladium in catalysts, alloys and complexesinfo:eu-repo/semantics/openAccessSociedad Chilena de QuímicaJournal of the Chilean Chemical Society v.53 n.3 20082008-09-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-97072008000300013en10.4067/S0717-97072008000300013
