Iron (II) Absorption from Groundwater by Natural Peat Soil at its in-Situ Conditions.(Dept.C)

Abstract

Contamination of groundwater with heavy metals may have harmful effects on the lives of people who depend on groundwater for drinking and other life purposes. Several techniques were used to remove the pollutants from the water, such as chemical precipitation, ion exchange, coagulation, electrochemical treatment, and adsorption. The last method is preferred due to its simplicity, easy recovery, and high effectiveness. Chemical analysis of the natural peat soil and the Fe (II) aqueous solution were performed. The characteristics of the soil were identified using X-ray diffraction (XRD), scanning electron microscope (SEM), and X-ray fluorescence (XRF). Furthermore, experimental work was carried out to investigate the effect of operational parameters on the removal efficiency% and adsorption capacity of natural peat to remove pollutants from aqueous solution. The operating parameters were the contact time, Fe initial concentration, adsorbent thickness, and adsorbent dose. The results explained that the natural peat soil was very effective for pollutant removal from an aqueous solution.
