الملخص الانجليزي
In this study low-cost composite was prepared from glass waste and activated carbon. The developed composite was used for the removal of heavy metals from well water in semi-arid regions. An effective new green composite adsorbent was synthesized by mechanical grinding of glass waste (GP) and activated carbon (AC), after hydrothermal treatment of the waste glass (TGP). Various ratios of AC to TGP composites (1:1, 2:1 and 1:2, respectively) were prepared. The ability of those new composites for heavy metal (Cd,Cu, Fe, Pb and Zn) removal was evaluated. Composite with the ratio AC to TGP (2:1) reveals the highest adsorption of the studied metals, so it was used for the rest of the experiments. The prepared composites were characterized by scanning electron microscopy SEM, XRD and BET surface area measurement. Batch experiments were conducted to test the ability of the new composites for the removal of Cd, Cu, Fe, Pb and Zn from its solution. The experiments of the heavy metals adsorption by the prepared composite were performed at different metal ion concentrations, solution pH, adsorbent dosage, solution temperature and contact time. By application of the new composite in well water, it reveals high removal efficiencies (99- 100%) for all the studied heavy metals at pH 7 contact time 45 min and a temperature of 25 °C.
