Clay minerals have been implicated as a probable active surface for pre-biological chemical reactions occurring during the early evolution of the Earth. In this context, it is very important to explain the role of these surfaces and how much a solid is involved in the chemical transformation that is taking place at its surface. The aim of this work is to present experimental results from the ultraviolet...
Cadmium adsorption features by montmorillonite and illite in alkaline conditions and the influence of inorganic salts were studied by experiment. The cadmium adsorption equilibrium time was 6 hours when the pH values in initiative solutions were 9, and the adsorption cadmium capacity by montmorillonite and illite was 6.910 mg.g-1 and 6.642 mg.g-1. When there are inorganic salts in the solutions of...
