The extraction behavior of N,N,N’,N’-tetrabutylglutaramide（TBGA）employing cyclohexane as diluent toward La（Ⅲ）,Pr（Ⅲ）,Gd（Ⅲ）and Er（Ⅲ） investigated.The effect of the concentrations of nitric acid,lithium n...The extraction behavior of N,N,N’,N’-tetrabutylglutaramide（TBGA）employing cyclohexane as diluent toward La（Ⅲ）,Pr（Ⅲ）,Gd（Ⅲ）and Er（Ⅲ） investigated.The effect of the concentrations of nitric acid,lithium nitrate and extractant and also the temperature on the extraction distribution ratio was studied.The stoichiometry of the extracted species was Found to be M（NO3）3·3TBGA（M=La,Pr,Gd,Er）.The extraction mechanism was also discussed and the values of the enthalpy of extraction reaction was calculated.展开更多
文摘The extraction behavior of N,N,N’,N’-tetrabutylglutaramide（TBGA）employing cyclohexane as diluent toward La（Ⅲ）,Pr（Ⅲ）,Gd（Ⅲ）and Er（Ⅲ） investigated.The effect of the concentrations of nitric acid,lithium nitrate and extractant and also the temperature on the extraction distribution ratio was studied.The stoichiometry of the extracted species was Found to be M（NO3）3·3TBGA（M=La,Pr,Gd,Er）.The extraction mechanism was also discussed and the values of the enthalpy of extraction reaction was calculated.
