- Abstract
The process of synergistic extraction of lithium from salt lake brine by tributyl phosphate⁃ethyl butyrate system was studied by response surface method with volume concentration of TBP, molar ratio of iron⁃lithium and phase ratio as independent variables and lithium extraction efficiency as response index.The optimal process conditions of the system obtained by response surface method were as follows:the volume concentration of TBP was 43%, the molar ratio of iron to lithium was 1.9 and phase ratio was 2.4.Under these conditions, the predicted value of lithium extraction efficiency was 92.39%, the actual measured valuewas 91.42%, and the relative error between predicted value and measured value was 1.05%.This study could provide a reference for the separation and extraction of lithium from salt lake brine.
