Biosorption to removing heavy metals from wastewater

Abstract

Abstract In this research, the efficacy of walnuts shell as bio adsorbent surface has been evaluated in the process of heavy elements removing from aqueous solution. Heavy metals concentrations are determined using X-ray fluorescence (XRF) techniques in walnuts shell and using the atomic absorption spectrometer to determined heavy elements concentrations in wastewater from the southern Rustumiya station, as Chromium (Cr), Nikel (Ni), Zinc (Zn), Copper (Cu), Mercury (Hg), Cadmium (Cd) and Lead (Pb). XRF technique is a viable and precise for analyzing a variety of harm materials and environmental samples with different advantages compared with conventional laboratory analysis ways.
