Study on La and Ce Distribution Ratio and Separation Factor in P204-HCl-H_3cit System AITranslate
Abstract AITranslate
In view of low separation factor of La（ Ⅲ ） and Ce（ Ⅲ ） in P204-HCl system, study was made of the effects of the feed solution acidity and citric acid（H3cit） concentration on the distribution ratio and the separation factor of La（ Ⅲ ） and Ce（ Ⅲ ）and the extraction capacity. The mechanism of the increase of the La （ Ⅲ ） and Ce（ Ⅲ ） separation factor was analyzed by FT-IR method. The experiment results showed that in P204-HCl-H3cit system,La and Ce distribution ratio and separation factor were lower with higher acidity but higher with higher citric acid concentration, while RE element extraction capacity was increased with higher citric acid concentration. With acid concentration 0.25 mol/L and feed acidity pH = 1.0, La and Ce separation factor was 4.1 ,and the maximum RE element extraction capacity was 24 g/L,which was superior to saponified P204-HCl system with the same acidity.
