Catalytic Degradation of Rhodamine B with Cobalt Phthalocyanine Supported Hydrotalcites

Abstract:

Rhodamine B is one of biodegradable azo dyes. In this thesis, the CoPc-LDHs were prepared by applying cobalt phthalocyanine on the Mg-Al hydrotalcites, and catalytic oxidation decolorization of rhodamine B (RhB) was studied. The results shown that compared with H₂O₂, CoPc-LDHs play a key role in catalytic oxidation of RhB. The optimal conditions about CoPc-LDHs/H₂O₂ system were H₂O₂ (30% w/w) 1.50 mL, pH 7 and 62.5°C. The catalytic oxidation decolorization effect of RhB reduced with the increase of initial concentration of RhB.
