The possibility of Pb2+, Cd2+, Ni2+ and Ba2+ ions removal from aqueous solution using light expanded clay aggregate (LECA) was investigated in this work. central composite design (CCD) response surface methodology (RSM) used to optimize the operating parameters (adsorbent granulometry, absorption time initial metal concentration) reach maximum single multi-elemental solutions. After optimizatio...

<p>Herein, the removal of heavy metals on thiol modified oak charcoal was investigated. The characterized by X-ray diffraction, granulometric analysis and infrared spectroscopy. Then, its adsorption efficiency for Cd2+, Cu2+ Pb2+ from water tested. effects several conditions were investigated such as contact time, pH, electrolytes initial metal ions concentration. capacities high (197, 25...

Heavy metals in the environment cause adverse effects on living organisms. Agro-wastes have potential to remove heavy from aqueous solutions. In this study, orange peel cellulose (OPC) beads were utilized as adsorbents wastewater. The surface of adsorbent was studied by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy coupled with energy dispersive x-ray (SEM-EDS...
