摘要A recyclable copper removal adsorbent was developed from diatomite and alu- minum sludge composite materials. The effects of different formulas on the adsorption of Cu2+ under different conditions were discussed. The properties and microstructures of the samples were characterized. The results showed that the optimum pH value, contacting time and raw materials proportion for copper removal are 6, 90 min and 40:60 (sludge: diatomite), respectively. The copper removal capacity could reach 0.46 mg/g at the initial copper concentration of 5 mg/L. There was no change in the composition of crystal phase before and after copper removal, so physical adsorption was dominant during the adsorption process.
