Sorption of Uranium on Some Natural Modified Clay Mineral Deposits.

Gas Sorption in Clay Mineral Systems

-Sorption isotherms for four gases (N2, A, Kr and C O 2 ) , commonly used in specific surface area and pore structure measurements, have been accurately determined on a number of clay mineral and oxide systems. Specific surface areas obtained by application of the BET theory to these isotherms illustrate the extent to which the apparent cross-sectional areas for these sorbed gases vary with sur...

Sorption of trivalent actinides on smectite rich natural clay

Metal Sorption on Mineral Surfaces: an Overview with Examples Relating to Mineral Deposits

Sorption reactions, involving both inorganic and organic particulates, are an important control on the transport and fate of many trace elements in natural systems. Understanding the controls on trace-element concentrations in waters is critical for a number of applications including the transport of contaminants and nutrients, geochemical prospecting, agriculture, municipal and industrial wate...

Application of Modified Clay for Sorption of Radionuclide Elements

The clay materials are distinguished on the basis of their different crystal structures. Due to their specific structure, they are applied in the nuclear industry for the removal of radionuclides from nuclear liquid waste as ion exchange material. This mini review presents some of the recent advances of various kinds of clay materials in this aspect. These inorganic materials continue to gain a...

Influence of Temperature on Nickel Sorption on Clay Mineral and Oxide

Introduction: Many kinetic studies have shown that sorption of metals on natural materials results in the formation of metal precipitates. However, the influence of temperature on the kinetic formation of these metal precipitates has not been studied. The effect of temperature on reaction rates is well known and important in understanding reaction mechanisms. For most reactions, the increase in...
