Preparation of La/Fe-Bentonite heterogenous Fenton catalysts for removing congo red in aqueous media
Keywords:
bentonite, congo red, fenton, heterogenous fenton, La/Fe-BentoniteAbstract
La/Fe modified bentonite material was synthesised by the simple ion exchange method and was applied to treat congo red in water. The characteristic properties was determined by XRD, thermal gravity, and BET. The lanthanum in material could increase the applicability in treating congo red in neutral and little base media. About 99% congo red could be removed after 1 hour. The factors during the treatment which were studied included pH, catalyst dosage, H2O2 dosage, and effect of Fe and La mol ratio in the catalyst.
