摘要
A method of spectrophotometric determination of micro amounts of platinum with MPT was proposed.Beers law is obeyed in the range of 0～3.7mg·L1Pt（Ⅳ）,an apparent molar absorptivity of ε682.0=5.46×104L·mol-1·cm-1.The method has been applied to the determination of platinum in minerals and catalysts with satisfactory results.
A method of speetrophotometrie determination of micro amounts of platinum with MPT was proposed. Beers law is obeyed in the range of 0 - 3. 7mg · L^-1pt（ Ⅳ ）, an apparent molar absorptivity of ε628.0 = 5.46 × 10^4L · mol^-1 · cm^-1. The method has been applied to the determination of platinum in minerals and catalysts with satisfactory results.
