Cation Exchange Equilibrium and Affinity Studies of Some Lanthanides(III) in Isopropanol Solvents

Abstract

Studies of cation exchange equilibrium and affinity of some lighter lanthanides e.g., lanthanum, cerium, praseodymium, neodymium and samarium ions in isopropanol solvents. Equili-brium exchanges studies were carried at room temperature in this way for La³⁺, Ce³⁺, Pr³⁺, Nd³⁺ and Sm³⁺ ions of three (0.1, 0.05 and 0.025 N) ionic concentration in aqueous isopropanol solvents and containing 10, 20, 30, 40 and 50 % (v/v) isopropanol and by using cation exchanges IC NAC-C-267, having 5.7 meg capacity and 40-60 mesh resin size.
