Rapid spectrophotometric determination of platinum with trifluoperazine dihydrochloride

Trifluoperazine dihydrochloride reacts with platinum(IV) in sodium acetate-hydrochloric acid buffer containing copper(II) catalyst to form a bluish-green 1:1 complex with absorbance maximum at 504 nm. A 50-fold ratio of reagent to metal ion is necessary for complete complexation. Beer's law is...

Summary:Trifluoperazine dihydrochloride reacts with platinum(IV) in sodium acetate-hydrochloric acid buffer containing copper(II) catalyst to form a bluish-green 1:1 complex with absorbance maximum at 504 nm. A 50-fold ratio of reagent to metal ion is necessary for complete complexation. Beer's law is valid over the concentration range 0.5-8 ppm of platinum(IV) with optimum concentration range 1-7 ppm. The molar absorptivity is 6.50 x 10(3) l.mole(-1).cm(-1). The effects of pH, time, temperature, concentration of reagent and copper, order of addition of reagents, and the interferences from various ions are reported.
