Effect of Alcohols on the Retention Mechanisms of Cd and

2005-8-9  The effects of ethanol− and methanol−water mixtures on Zn and Cd sorption onto bentonite and illite were investigated at low initial metal concentration (≤10-5 M) and low ionic strength (2.5 mM Ca(NO3)2). For all cosolvent fractions, the percent coverage of Zn and Cd to clay minerals was low (<5%) and independent of the solution dielectric constant, ε, except for Zn at 10 μM. Cadmium

Ti-montmorillonite as photocatalyst to remove 4

2004-9-30  We studied the photocatalytic activity of Ti-montmorillonite. The highest activity was found for a Ti/bentonite ratio of 10 mmol/g, prepared using HCl and calcined by microwaves. This mixture is less active than TiO2 P-25 for 4-chlorophenol removal in water, but more active for methanol removal in air.

Kinetics of mercuric chloride retention by soils (Journal

Abstract. A nonlinear multireaction model was used to describe kinetic data for HgCl{sub 2} retention by five soils. A three-parameter version of the model consisting of a reversible nonlinear (nth order, n < 1) reaction and an irreversible first-order reaction was capable of describing HgCl{sub 2} retention data for Cecil (clayey, kaolinitic, thermic Typic Kanhapludult) and Windsor (mixed
