Abstract

Synergistic extraction method has been developed for the extraction of Eu(III) from buffer solution of pH 3 using 1 M synergic mixture of di-n-butylsulfoxide (DBSO) and Cyanex-272 in chloroform. The extracted europium was measured spectrophotometrically by using 0.01 % solution of arsenazo(III) in 3 M perchloric acid as chromogenic reagent. Various parameters such as pH, shaking time, extractant metal ion concentration, cationic, anionic effects and temperature effects were optimized on extraction of Eu(III) among various cations. Only Sr(II), Ni(II) and Fe(III) interfere in the extraction process. Anions such as fluoride, oxalate and thiosulphate interfere on extraction of Eu(III). Deionized water was found to be the most suitable stripping agent for europium back extraction due to its economical suitability and easy and comparatively good refining of europium from organic phase. The extraction was found to be almost independent of the metal ion concentration in the range studied (6.6 × 10-4 to 6.58 × 10-3 M). The composition of the extracted species was found to be Eu(C272)3·2DBSO. The accuracy of the method proposed has been checked by determining concentration of standard europium solution in the range of 100-4000 ppm. It was noted that per cent deviation decrease with increasing concentration of metal ions. The recycling capacity of the organic solvent was checked and found to be excellent without any degradation.
