Cation exchange in the synthetic gismondine-zeolite MAP

Dyer, A; Heywood, B; Szyrokyj, N

Abstract

The synthetic gismondine-zeolite MAP is a bulk chemical used as a detergent additive. This work examines the uptake of silver and manganese cations, as relevant to its potential slow-release antifungicidal/bacteriological application.

Silver uptake induced structural degradation of the zeolite framework, even at low cation exposures. Manganese was selectively exchanged at low solution phase concentration, and accompanied by secondary formation of manganese oxide/hydroxide phases. The possible mechanisms involved are discussed, and suggestions made as to the nature of the manganese phase.
