Production of silver-loaded zeolites and investigation of their antimicrobial activity
… zeolites either by ion exchange method or by isomorphous substitution of silver ions into zeolites frameworks and their antimicrobial activity is presented. Silver-loaded zeolites produced by ion-exchange in this work include silver-exchanged zeolite X, silver-exchanged zeolite A and …

The modification of Laponite® with silver or copper and investigation of their antibacterial activity
… RD were synthesised either by ion exchange or isomorphous substitution into Laponite® RD sheet. Six different concentrations of silver-exchanged Laponite® RD (AGLAP1-6) or copper exchanged Laponite® RD (CULAP1-6) were produced in this work via ion exchange and three different concentrations of …

Chemical modification of smectite clays
… examined. For Wyoming bentonite the extent of isomorphous substitution increases with decreasing particle size, causing the CEC to similarly increase, although the isomorphous substitution site: edge site ratio remains invarient throughout the particle size range studied.

Caesium and strontium exchange at specific clay mineral sites
… minerals with a net negative charge arising from isomorphous substitution within the crystal lattice, caesium and strontium sorption is predominantly a cation exchange process. Strontium exchange with charge compensating sodium ions on clay minerals, in the absence of competing cations, results in …

Exploitation of synergy in oxidation catalysis with bimetallic aluminophosphate catalysts
… catalysts were prepared with the simultaneous isomorphous substitution of cobalt (III) and manganese (III) for aluminium (III) and titanium (IV) replacing phosphorus (V). By substituting simultaneously for both Al (III) and P (V) in the ordered microporous aluminophosphate AlPO-5, the potential …
