| Abstract: |
| The waste water effluents from industrial establishments containing all types of hazardous substances including heavy metals which have given rise to various diseases. The sorption of Pb, Zn and Ni from aqueous solutions on mineral soil has been studied in different amount of sorbent, pollutant and time of reaction it should be noted that all reactions were carried out at room temperature. All these mineral wastes have been characterized by X-ray diffraction and inductively-coupled plasma and subsequently, adsorption of heavy ion was measured by Atomic Adsorption Spectroscopy (AAS).various soil from different part of mine have had different behavior of ion adsorption in comparison with each other i.e. the soils do not have ability to adsorb Ni contrary to Pb and Zn . The experimental results were confirmed an uptrend in adsorption rate by increasing the time of reaction and amount of sorbent until amount of adsorption become equal with these two parameters. Langmuir isotherm was achieved by using of equilibrium amounts of each parameter for three soils that are most efficient. The contrast between X-ay diffraction pattern and ability of adsorption were showed that albeit phase plays the most important role in adsorption process. As a result, the equilibrium amount of Pb and Zn were around 550 ppm and 400 ppm respectively. |
