Organomineral Sorbents Based on Clinoptilolite-Containing Tuffs and Polyethylenimime

Organomineral Sorbents Based on Clinoptilolite-Containing Tuffs and Polyethylenimime Low-swelling sorbent with weakly basic anion-exchange properties was prepared from clinoptilolite-containing tuffs and polyethylenimine using epichlorohydrin cross-linking agent. The properties of this sorbent (total anion-exchange capacity, swellability, etc.) were studied as influenced by the concentrations of the modifying and cross-linking agents, their ratio, period after sorbent preparation, and number of sorption-desorption cycles. The optimal conditions for modifying clinoptilolite-containing tuffs were developed and elemental composition of the resulting sorbent (with respect to C, H, and N) was determined.
