Paper Title:
Study of Adsorbent Derived from Sewage Sludge Incineration Residue for the Removal of Ni2+ in Wastewater
  Abstract

Sewage sludge incineration residue was obtained from a sewage treatment plant in Guangzhou and used as a low-cost sorbent for removing Ni2+ from wastewaters. The adsorption effectiveness and their factors of Ni2+ in aqueous solutions were simulated detailed using the adsorbents of the sludge incineration residue. The simulation contents and the factors included the adsorption time, the pH of solution and the dosage of adsorbents and so on. The results showed that at room temperature, the adsorption equilibrium of Ni2+ can be achieved in 6h and the best pH value of the solution was about 7.0. The removal rates of Ni2+ were increased with the adsorbent concentration increasing and the optimal concentration of adsorbent was 10g/L with the initial concentration of Ni2+ less than 30mg/L.At the best adsorption conditions, the removal rate of Ni2+ reached more than 70%.
