Solvent extraction of praseodymium (III) from sodium salicylate medium using organophosphorous extractant cyanex 301 in chloroform was studied. The effects of various parameters like sodium salicylate concentration, extractant concentration, shaking time, diluents and stripping agent on the extraction efficiency of Pr (III) were investigated, Diverse ion study was also performed in order to check the influence of other ions in the extraction. The extraction of Pr (III) was quantitative using 0.003 M Cyanex 301 and 0.01M sodium salicylate. The extracted Pr (III) was stripped out quantitatively from the organic phase with 1.0 M hydrochloric acid and determined spectrophotometrically with arsenazo (III) at 655 nm. Separation of Pr (III) from binary mixture other was achieved The method was extended for the separation and determination of Pr(III) in magnet leach solution. The method is simple, rapid and selective with good reproducibility.
