Abstract
- Waste residue of Chinese prickly ash seeds were simply treated with aqueous ZnCl <subscript>2</subscript> to prepared the high-performed activated carbon. It was characterized by the methods of XRD, SEM, EDX, FT-IR, BET and XPS. The synergetic adsorption performance of Chinese prickly ash seeds activated carbon for Pb <superscript>2+</superscript> , Ni <superscript>2+</superscript> and Acid Orange IΙ (AO) was studied. In the single-component system, the adsorption capacity of Pb <superscript>2+</superscript> , Ni <superscript>2+</superscript> and AO were 15.1, 10.7 and 188.4 mg/g, respectively. In the AO-Pb <superscript>2+</superscript> system, the maximum adsorption capacity of Pb <superscript>2+</superscript> and AO were 79.40 and 332.68 mg/g under temperature of 30°C and pH of 5.0, respectively. For AO-Ni <superscript>2+</superscript> system, it was 375.6 and 38.3 mg/g, respectively. The adsorption kinetics was satisfactorily fitted by the pseudo-second-order model. The synergic adsorption process can be smoothly described by the non-modified Sips isotherm.
