Dehydration, Diffusion and Entrapment of Zinc in Bentonite
Bentonite Entrapment Interaction Micropore Diffusion Speciation Zinc
2011/12/8
Abstract: Interactions with bentonite are important in the chemical speciation and fate of heavy metals in soils and other ecosystems. The interactions of Zn with bentonite were studied using X-ray di...

The crystal structure of namuwite, (Zn,Cu)4S04(OHk4H20, trigonal, a = 8.331(6), C = 10.54(1) A,V=634(1) A3,Pj, Z = 2, has been solved by direct methods and refined to an R index of 7.9% using MoKa X-r...
Effect of pH on Zinc Adsorption and Solubility in Suspensions of Different Clays and Soils
Zinc Adsorption Solubility pH Clays Soils
2011/11/14
Zinc solubility in clay and soil suspensions was controlled by chemi-sorption at pH 4.5 - 7.0. Thesolubility in clay mineral suspensions was in the order
palygorskite < montmorillonite < kaolitlite a...
Selective Adsorption of Zinc on Halloysite
Adsorption Cation exchange Halloysite Selectivity Zinc
2012/2/9
Zn- and Ca-adsorption equilibria of five Ca-saturated halloysite samples were measured at equilibrium Zn concentrations up to 10−2 M in 10−4 to 10−2 M CaCl2. The results were interpr...
Reactions of Zinc with Acid and Base Saturated Dickites
Adsorption Dickite Exchange Sodium Zinc
2012/2/10
The effect of pH, time and temperature on the interaction of zinc with acid and base saturated dickites has been investigated. Increase in pH resulted in an increase in adsorption of zinc in the highe...
