Spectrophotometric Study on the Determination of Palladium with 4 -(5-Bromo-2-Pyridyl)-Azo-1,3-Diaminobenzene

Abstract:

This document develops a new spectrophotometric method for the determination of palladium with 4-(5-bromo-2-pyridyl)-azo-1,3-diaminobenzene, in a medium of 1.80mol/L sulfuric acid, at the maximum wavelength of 566nm. Absorption spectra of reagent and complex, effect of acidity, composition of complex and heating time for color reaction are discussed. More than 30 kinds of interfering ions are determined. The interference of Pb²⁺, Ag⁺ and Cr⁶⁺ are eliminated effectively by the proposed method. Beers law is obeyed in the concentration ranges of 0-1.0mg/L for palladium, the molar absorption coefficient is 6.44×10⁴Lmol^-1cm^-1. The method is applied to the determination of palladium in general ores and palladium catalysts.
