摘要：

A direct spectrophotometric method has been developed for the determination of platinum using thiocarbohydrazide as complexing reagent. Platinum reacts with thiocarbohydrazide in the pH range of 5.5-8.0 and in the ratio of 1:2 (metal:ligand). It absorbs strongly at 495 nm. Beer's law is obeyed over the concentration range of 2.0-11.22 ppm. The molar absorptivity and Sandell's sensitivity are calculated to be 6.4 x 10(3) L.mole-1 cm-1 and 0.0029 mug/cm2. The method has been applied for the determination of platinum in various synthetic samples.
