title: The determination of platinum in reforming and emission-control catalysts by differential spectrophotometry.
abstract: Differential spectrophotometry is used in conjunction with the stannous chloride method to determine platinum with < 1% relative error in reforming and emission-control catalysts. Detailed instructions are given for decomposition of the samples.
