Abstract

EXTRACTIVE SPECTROPHOTOMETRIC DETERMINATION OF PLATINUM (IV) USING 2-(5- BROMO-2- OXOINDOLIN-3-YLIDENE) HYDRAZINE CARBOTHIOAMIDE AS AN ANALYTICAL REAGENT

ABSTRACT

A simple, rapid and sensitive spectrophotometric method has been developed for the determination of Pt(IV) by using 2-( 5-Bromo -2- Oxoindolin-3-ylidene)Hydrazine Carbothioamide or 5-BromoIsatin thiosemicarbazone [HBITSC] as an analytical reagent. [HBITSC] has been synthesized and characterized by elemental and spectral analysis. [HBITSC] extracts Pt (IV) quantitatively (99.67%) into n-amyl alcohol from an aqueous solution of pH range 3.0-6.0 and in the presence of 3cm3 of acetic acid-sodium acetate buffer (pH 4.6). The n-amyl alcohol extract shows an intense peak at 505 nm (λ max).Beer’s law is obeyed over the Pt(IV) concentration range of 1.0-9.0 μg/cm3 The Sandell’s sensitivity and molar absorptivity for Pt -HBITSC system is 23.07ngcm-2 and 8452.53 L mole-1cm-1 respectively. The composition of extracted species is found to be 1:2 [Pt:HBITSC] by Job’s Continuous Variation and Mole Ratio Method. Interference by various ions has been studied. The proposed method is rapid, sensitive, reproducible and has been successfully applied for determination of Pt(IV) in catalyst samples.

Keywords: Extractive Spectrophotometry, Pt(IV), 5-Bromo Isatin thiosemicarbazone [HBITSC], Samples.
