[Sorption properties of carboxyl cation exchangers with a bacteriostatic effect]

Sorption properties of new carboxyl cation exchangers containing components of salicylic acid (CST and CMTS) and benzoic acid (CBT and CMTB) were examined with respect to large organic ions. Such cation exchangers were shown to have greater permeability for high molecular weight proteins that sorbents of the Biocarb type. Bacteriostatic properties of the above cation exchangers were studied. With an increase in the content of the bactericidal component the bacteriostatic effect of the cation exchangers on Escherichia coli and Staphylococcus aureus enhanced. The cation exchangers CST and CMTS showed a greater bacteriostatic effect than those CBT and CMTB.
