ORGANIC/MINERAL ION EXCHANGER FOR WATER CLEANING AND DISINFECTION AND METHOD FOR MAKING THE SAME Russian patent published in 1995 - IPC

FIELD: water cleaning, softening and DISINFECTION. SUBSTANCE: natural zeolit-clinoptilolite is used as a carrier, and polyhexametylenguanidinehydrochloride structured with epichlorhydrin in alkali medium characterized cation exchange and anion exchange capacity, able to decrease microbe impurity is used as polymeric modifier in the organic/mineral ion exchanger as a product of modifying mineral carrier with water-soluble nitrogen bearing polymer. Modifying process is carried out subsequently by processing clinoptilolite with aqueous solution of polyhexametilenguanidine with subsequent structuring the obtained product with epichlorhyrin in the presence of alkali and washing the obtained product up to neutral reaction of the spent water to obtain organic/mineral ion exchange process. EFFECT: high efficiency. 3 cl, 1 dwg, 7 tbl
