REMOVAL OF A BINARY DYE MIXTURE OF CONGO RED AND MALACHITE GREEN FROM AQUEOUS SOLUTIONS USING A BENTONITE ADSORBENT

open access: yes, 2009
An important application of clay is as a solid adsorbent for industrial dyes. The aim of the present work was to carry out an experimental-theoretical study of the adsorption of dye mixtures, namely malachite green (MG) and Congo red (CR), by bentonite ...

Towards an understanding of thermodynamic and kinetic controls on the formation of clay minerals from volcanic glass under various environmental conditions [PDF]

open access: yes, 1996
lmogolite is the kinetically and thermodynamically favoured weathering product from rhyolitic volcanic glass in the soil-forming environment. However, on thermodynamic grounds imogolite would also appear to be the favoured alteration product of rhyolitic

Anion diffusion pathways in bentonite clay compacted to different dry densities

open access: yes, 2003
Diffusion of the anions Cl- and I- in MX-80 compacted bentonite has been studied at different ionic strengths (0.01, 0.1 M NaClO4) and clay density (0.4, 0.8, 1.2, 1.8 g cm(-3)) at the buffered pH of bentonite 8.2 using a through-diffusion technique with

Biofilm formation of Pasteurella multocida on bentonite clay.

open access: yesIranian journal of microbiology, 2013
Biofilms are structural communities of bacterial cells enshrined in a self produced polymeric matrix. The studies on biofilm formation of Pasteurella multocida have become imperative since it is a respiratory pathogen and its biofilm mode could possibly be one of its virulence factors for survival inside a host.
