Separation of La(Ⅲ),Ce(Ⅳ)and Ca(Ⅱ)from bastnaesite using acidic phosphonic chitosan and rotating disk membrane
《Journal of Rare Earths》2024年第5期995-1000,I0007,共7页Dandan Lu Wenhui Li Linlin Fan Yunren Qiu 
Project supported by the National Natural Science Foundation of China(22178392);the Fundamental Research Funds for the Central Universities of Central South University,China(2022ZZTS0493)。
The separation of rare earths is difficult due to their similar properties and the complex characteristics of associated vein o res.Complexation-ultrafiltration(CUF)and shear induced o rderly dissociation coupling wit...
