Water decontamination by silver and copper montmorillonite

Several bactericide inorganic materials have been used for the purification of water with varying success. The characterisation of the incorporation of Ag or Cu cations in montmorillonite (MMT) clay, to obtain a bactericide material against E. coli, indicated that both outer and interlayer surfaces...

Experiences from supernatants of Cu-exchanged clays indicated that bactericide capacity was present at high clay concentration. Copyright © 2014 Inderscience Enterprises Ltd. Fil:De La Fournière, S.
