The Use of Some Food Industrial by Products for Waste Water Purification
A.B.S. Al-Barak and S.M. El-Said

Abstract: Most available technologies applied in the removal of metal contaminants in aqueous systems use the well established processes of adsorption. Adsorbents currently in use are either too expensive or not readily available for waste water treatment. There is a need to develop new adsorbents which are readily available at low cost to remove metal contaminants in aqueous system. In this work, okra wastes as a food canning processes by products were used as a potential adsorption of cadmium (II), iron (II) and zinc (II) removal from various aqueous solutions. Qualitative and quantitative analysis of okra wastes were investigated. Infrared spectra of the okra wastes were recorded to detect the function group that gained the capabilities of okra wastes for metal ion adsorption. Batch studies were performed to evaluate the adsorption process and it was found that the okra wastes were found to adsorb 96.4% of cadmium (II), 93.8% of iron (II) and 79.8% zinc (II). The rate of adsorption follows pseudo-second order kinetics before attaining equilibrium. This work proved that okra wastes can be used as an efficient adsorbent material for removal of heavy metals from water and waste water.
