摘要：

A sensitive and selective procedure for spectrophotometric determination of platinum (IV) with rhodamine 6G in presence of iodide has been described. The absorbance is measured at 575 nm and the molar absorptivity is found to be 1.26x10(5) l mol(-1)cm(-1). The complex system obeys Beer's law in the range 0-12 mu g of platinum (IV) present in 25 ml of final solution. The effect of pH and concentration of iodide and rhodamine 6G have been studied. The method has been applied successfully to the determination of platinum (IV) in the standard platinum carbon powder (platinum catalyst).
