Аннотация

The possibility of purifying lithium-containing solutions to remove chemical impurities by sorption in the batch mode was examined. Sulfonic (KU 2-8, Purolite C100, Resinex KW-8), carboxylic (SG-1, Purolite C104FL, Resinex KW-H), and phosphoric acid (Purolite S957) cation-exchange resins were used as sorbents. The distribution coefficients of lithium and impurity elements (sodium, potassium, magnesium, calcium, iron) at different pH values were determined experimentally. The lithium/impurity separation factors were calculated.
