Abstract

Extraction of lanthanides(III) from aqueous solutions of nitric and perchloric acids and bis[(trifluoromethyl)sulfonyl]imide with solutions of N,N '-dimethyl-N,N '-dicyclohexyldiglycolamide in organic solvents was studied in relation to the concentration of acids in the aqueous phase. The stoichiometry of the extracted complexes was determined. It was found that the transformation of N,N '-dimethyl-N,N '-dicyclohexyldiglycolamide into a complex with bis[(trifluoromethyl)sulfonyl]imide leads to a significant increase in the extraction of lanthanide(III) ions from solutions of nitric, hydrochloric, sulfuric, and phosphoric acids.

N，N'-二甲基-N，N'-双环己基二甘醇酰胺配合物-双[（三氟甲基）磺酰基]亚胺萃取无机酸溶液中的镧系元素(III

研究了有机溶剂中N，N '-二甲基-N，N '-双环己基二甘醇酰胺溶液从硝酸、高氯酸和双[（三氟甲基）磺酰]亚胺水溶液中萃取镧系元素（III）与水相中酸浓度的关系。测定了萃取物的化学计量学。研究发现，N,N '-二甲基-N，N '-双环己基二乙醇酰胺与双[（三氟甲基）磺酰]亚胺的配合物的转化导致从硝酸、盐酸、硫酸和磷酸溶液中提取镧系（III）离子的量显著增加。
