Abstract

The extraction equilibrium of lithium with 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester, commercial name PC-88A, was investigated, as well as the extraction kinetics of lithium using a hollow fiber membrane extractor, in order to develop a recovery process for lithium from geothermal water or wastewater from lithium carbonate precipitation in the recycling process for spent lithium batteries. It was found that lithium is extracted by a heptane solution containing PC-88A, (HR), according to the following equation, Li+,aq + 2(HR)2,org → LiR(HR)3,org + H+ ,aq where (HR)2 is the dimer of PC-88A. Furthermore, the extraction mechanism of lithium through the hollow fiber membrane was elucidated.
