Va. Nikashina et al., ORGANOMINERAL SORBENTS BASED ON CLINOPTILOLITE-CONTAINING TUFFS .1. PREPARATION OF ORGANOMINERAL ANION-EXCHANGERS USING POLYHEXAMETHYLENEGUANIDINE, Russian chemical bulletin, 43(9), 1994, pp. 1462-1465
A practically nonswelling sorbent with anion-exchange properties based
on clinoptilolite-containing tuffs and polyhexamethyleneguanidine has
been obtained. Its total anion-exchange capacity has been studied as
a function of the ratio of the modifier and cross-linker concentration
s, the deposit of the clinoptilolite-containing tuff, and pretreatment
of its surface. The anion-exchange capacity of the sorbents reaches 0
.22 meq. mL(-1). The conditions for the synthesis of the sorbent have
been chosen, and the elemental composition of the samples obtained has
been determined.
