  • Evaluation of Heavy Metals Removal Using Some Egyptian Clays

    Bentonite is an adsorbent aluminum phyllosilicate and is mainly composed of montmorillonite (smectite) with some other clays and inorganic minerals. Types of bentonites depend on their dominant elements (K, Na, Ca and Al). Such clay minerals in soil play the role of natural scavenger by removing and accumulating contaminants in water passing
