ABSTRACT
Organomineral ionites have been synthesized, in which natural mineral sorbent is chemically bound to organic part of a molecule, containing ionogen groups. Ionogen groups of these ionites contribute to efficient exchange in water solutions. They might be used for cleaning drainage waters and technical solutions, as well as for purification of medicinal preparations from various admixes. Hydrogen forms of natural zeolite – clinoptilolite and bromoacetic acid were used to resolve this problem. Chemical
modification of clinoptilolite, by inculcation of ionogen groups into zeolite skeleton, enables us to increase significantly ionite exchange capacity. Static exchange capacity of a cationite with carboxyl ionogen groups increases from 0.1-0.9 (for chemically unmodified zeolite) to 5-6 mg-equiv/g.
