Abstract

A simple and selective solvent extraction method has been derived for selenium (IV) and tellurium (IV) by sequential mode from each other as well as from other accompanying elements. N-n-octylcyclohexylamine (N- n -OCA) has been used for quantitative extraction of selenium (IV) and tellurium (IV) in dichloromethane (DCM) - xylene solvent mixture. The quantitative extraction of selenium (IV) was observed in the acidic range of 0.4 - 0.8 M hydrochloric acid (HCl) with 0.05 M N- n - OCA in DCM - xylene. Whereas that of tellurium(IV) was observed in the acidic range of 6.8 to 7.5 M HCl. Selenium(IV) and tellurium(IV) from the organic phase were stripped with 1:1 NH3 and determined spectrophotometrically with 1-(4'-Bromophenyl)- 4,4,6-trimethyl-1,4- dihydropyridine-2-thiol (4'-bromo PTPT) at 350 nm and 440 nm, respectively. The optimum extraction conditions were evaluated by a critical study of acidity, extractant concentration, period of equilibrium and effect of diluents. Sequential separation of selenium(IV) and tellurium(IV) has been achieved taking the advantage of difference in acidity for the extraction flow sheet - I. The separation of these metal ions from one another in varying ratio of selenium(IV) : tellurium(IV) and multi components mixture of commonly associated metals was found to be possible by this method. It was successfully applied for analysis of selenium(IV) and tellurium(IV) in real sample such as alloys, pharmaceutical samples and thin film.
