| titleOfInvention | Mixed extracting agent and method for separating rare earth yttrium |
| abstract | The invention provides a mixed extracting agent, which comprises: naphthenic acid compounds and alkyl phenoxy propionic acids. The invention provides a method for separating rare earth yttrium, which comprises the following steps: extracting with organic phase-rare earth mixed liquid to make yttrium element enter water phase; the organic phase comprises a mixed extractant and diluent. According to the invention, the naphthenic acid compound and the alkyl phenoxy propionic acid are compounded to obtain the mixed extractant, and the naphthenic acid compound and the alkyl phenoxy propionic acid can generate a synergistic effect, so that the separation selectivity of rare earth yttrium is improved, and a better rare earth separation effect is achieved. |
