FIELD: technological processes; chemistry.
SUBSTANCE: fine-grained zeolite of A-LSX type with crystal size of 0.9-3.0 micrometer is mixed with carboxymethyl cellulose (CMC), taken in the amount of 3-15 wt % in conversion to dry zeolite. Mixture is extruded. Granules are dried at 130-180°C, crushed and fractionated for production of end product with particle size of 0.2-2.5 micrometer. Fraction of particle with size below 0.2 mm are returned to mixing with CMC.
EFFECT: increase of cation-exchange efficiency.
