Abstract:

Simple, rapid and sensitive solvent extraction and spectrophotometric determination method has been developed for the determination of Os(VIII) using P-Methylphenyl Thiourea (PMPT) as an analytical reagent. PMPT has been synthesized and characterized by spectral analysis. PMPT extracts Os(VIII) quantitatively into chloroform from perchloric acid media. The chloroform extract shows an intense peak at 512 nm (? max). Beer???s law is obeyed over the Os(VIII) concentration range of 60 ?g/mL. The molar absorptivity and Sandell???s sensitivity for Os(VIII)-PMPT system is 6.826??103 L mol-1cm-1 and 0.028 ?g cm-2 respectively. The composition of extracted species is found to be 1:1 (Os(VIII): PMPT) by slope ratio method, job???s continuous variation and mole ratio method. Interference by various ions has been studied. The proposed method has been successfully applied for determination of Os(VIII) in synthetic samples. Sequential separation of Palladium(II), Osmium(VIII) and Platinum(IV) is carried out by using proposed method.
