Abstract: 

Heavy metals pollution is a topic with worldwide concern because of its high toxicity to human beings, animals, and plants. The clay minerals, being important constituents of soil, have been playing this role always by taking up various contaminants as water flows over soil or penetrate underground. The high specific surface area, chemical and mechanical stability, layered structure, high cation exchange capacity (CEC), Bronsted and Lewis acidity, etc., have made the clays excellent materials for adsorption. In this study, retention process of Cd (II) contaminant using Bentonite and Nanoclay Cloisite Na+ investigated. Based on data obtained in this study it can be concluded that the retention capacity of Nanoclay Cloisite Na+ is much more than Bentonite for Cd ions, because of high specific surface area and high cation exchange capacity of Nanoclay Cloisite Na+.
