With stannous chloride as chromogenic agent, platinum in gray platinum network was determined with spectrophotometry. When selecting the appropriate experimental conditions, accurate of platinum and reproducibility were high, the calibration eurvecorrelation coefficient was greater than 0. 999, the precision was better, and quantitative determination of the scope was 0 -50 mg/kg. This method for determine platinum in waste gray platinum network was simple, fast, good selectivity, and with satisfactory results.
