DETERMINATION OF SULFATE CONCENTRATIONS IN CHROMIUM PLATING SOLUTIONS WITH RADIOACTIVE ISOTOPES

Abstract

A radioctive isotope dilution method for determination of sulfate concentration in chromium plating solutions was developed to overcome coprecipitation difficulties experienced with the BaCL< PRECIPITATION METHOD. The method developed had a 2.4% average error, considered satisfactory for the type of analysis, reduced analysis time to 2 hr, and had reproducibility comparable with other methods used for the determination of sulfate concentrations in Cr plating solutions. Details of the methods are given. (Author)
