Abstract
The extraction of cerium with acetylacetone was studied, using 144Ce as a tracer. Cerous cerium can not be extracted without an oxidizing agent. After the mixture of 0.61 m sodium Bromate and 5×10−6m cerium had been left standing for 100min. at pH 5∼6, 95% of the cerium was extracted in benezene.The reaction was accelerated by heating, e.g., at 40°C, or by increasing the concentration of acetylacetone and bromate. Care should be taken not heat too long. this avoiding the decomposition of the chelate by hydrolysis.The presence of phospate, oxalic acid, Citric acid, tartaric acid and EDTA causd interference.This publication has 1 reference indexed in Scilit:
