英文摘要The adsorbent ability of Al(2)O(3)nanoparticles (ANPs) was examined to remove Cd(2+)and Zn(2+)from aqueous solution. The sorption of Cd(2+)and Zn(2+)on ANPs as a function of pH, ionic strength (IS), humic acid (HA), contact time, foreign ions and the temperature were investigated. It was observed that physico-chemical factors (pH and ionic strength) strongly affect the sorption of Cd(2+)and Zn(2+)on ANPs. Comparatively, the sorption of Cd(2+)and Zn(2+)dominated by surface complexation of the outer sphere at low pH values (pH < 8.0), while surface complexation of the inner sphere was the major sorption mechanism at elevated pH values (pH > 8.0). The maximum sorption capacity of Cd(2+)and Zn(2+)on ANPs calculated from the Langmuir model was 8.40 and 9.00 mg g(-1)respectively at 303 K, exhibiting higher efficiency for Zn(2+)sorption than Cd2+.The thermodynamic parameters ( increment H-0, increment S(0)and increment G(0)) showed that the adsorption of Cd(2+)and Zn(2+)was endothermic and spontaneous. This investigation exhibited that ANP is an efficient, inexpensive process and thereby reasonable technology for the elimination of metal ions from the contaminated aqueous source.
