摘要：
The removal of Acid Orange 7 dye from water using the macroporous strongly basic anion exchange resin was investigated using the batch method with a particular reference to the effects of the initial dye concentration, the phase contact time, temperature, pH, the presence of inorganic salts (NaH(2)PO(4), Na(2)HPO(4), Na(2)SO(4)) and surfactants (SDS, CTAB, Triton-100) on adsorption. Next, the desorption of the dye adsorbed on the anion exchanger was studied using the batch method by testing different solutions, namely aqueous and aqueous-methanol solutions of HCl. NaOH, and NaCl. Also the anion exchanger behavior with artificial and real wastewater samples was studied with very promising results. (C) 2011 Elsevier B.V. All rights reserved.
