SELECTION OF ION-EXCHANGE RESIN FOR EXTRACTION OF REE FROM COMPLEX SOLUTIONS DURING PROCESSING OF OIL CRACKING CATALYST
It was found that the ion exchange resins Purolite C100 H and Purolite S-957 can be used to extract lanthanum (III) ions from solutions. The values of the resin capacities for lanthanum (III), iron (III) and aluminum and the ion distribution coefficients for both resins were determined. It is shown that according to the values of the separation coefficients, Purolite C100 H resin can be used for ion exchange separation of lanthanum ions from complex solutions
