In this work, γ-Al2O3powder as copper adsorbent material was synthesized from polyoxohydroxide aluminum (POHA) precursor using aluminum powder, potassium hydroxide and d- glucose dissolved in distilled water and ethanol, and calcined at 500 °C. Prepared γ-Al2O3powder was characterized using (XRD), (FTIR), (SEM), (LGI) and (BET) method. The copper ions concentration of oilfieldproducedwater was determined using (ICP-OES). The parameters considered asγ-Al2O3adsorbent dose, adsorption time and pH used in this work are (0.2 and 0.4 mg/l), (30-180 min) and (4-10 pH) respectively. The characterization results showed that γ-phase is the dominant phase of synthesized Al2O3 powder. The results also showed that high adsorption performance for copper ions with a high removal efficiency of 99.99% using synthesized γ-Al2O3was obtained with an absorbed dose of 0.4 mg /l, adsorption time of 90 min and a pH of 7.Refference:
