Abstract In Egypt, the increase in industrial activities over the past years has contributed significantly to the deterioration of environmental conditions in urban conglomerates and localities nationwide. As anticipated, these industrial activities increase was accompanied by an increase in ambient pollutants levels and generation of large amounts of hazardous waste. With the lack of a system to regulate the handling or disposal of the generated wastes, each industrial facility was left unchallenged to devise its own waste management procedures. Recently, many naturally occurring materials have been used for different decontamination purposes. The natural clay mineral is considered as a good ion exchanger since it is easily found and have low cost and high capacity in removing the heavy metals and organic compounds. The objective of this work is to study the sorption behavior of some heavy metals present in the industrial waste solutions using some clay minerals materials collected from different locations in Egypt. In this concern, Five clay samples collected from Sinai, El-Saff, EI- Payoum, Bahryia and Aswan were used for this study. The adsorption studies were carried out in two stages. In the first stage batch process equilibrium was carried out for single component using synthetic solutions with initial concentrations in the range between 2.5 to IOmg/l ofPb2+, Fe3+ .ce” and Zn2+ respectively. |
