Abstract
Sorption behavior of neodymium (Nd) from cerium (Ce) and samarium (Sm) on anion-exchange resins was investigated by column techniques. The anion exchange studies involved the sorption of Nd, Ce and Sm ions onto Dowex 1-X4 (100–200 mesh) in nitric acid – methanol medium. Separation of neodymium from cerium and samarium was carried out by column method to find out the best separation parameter condition with variating HNO3 concentration and weight of resin. The best elution profile was found using 0.3M HNO3 : methanol (1 : 9) as eluent through 1.25 grams of Dowex 1-X4 resin with 97.16 % Sm recovery and 95.59 % Nd recovery, while Ce was retained in the column.
