Abstract
A new efficient catalyst, CoTSPc@chitosan, was developed by immobilizing water soluble cobalt (II) tetrasulfophthalocyanine onto adsorbent chitosan microspheres covalently for the heterogeneous catalytic oxidation of C. I. Acid Red 73 with H(2)O(2). The result indicated that the COD removal and discoloration of C. I. Acid Red 73 made 55 and 95% respectively in the presence of CoTSPc@chitosan with H(2)O(2) in 4h. In addition, CoTSPc@chitosan-H(2)O(2) system could proceed efficiently in a relatively wide pH range and remain high catalytic activity after 6 reuse cycles. Furthermore, the adsorption study of CoTSPc@chitosan confirmed that chitosan was an outstanding support which contributed a lot to the removal reaction. In conclusion, the combination of adsorption process and catalytic oxidation made the CoTSPc@chitosan-H(2)O(2) system achieve a simple, efficiently and environmentally friendly water treatment.
