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...
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...
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...
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...
