Preparation of Particle Reusable Heterogeneous Catalyst Fe3O4/ATP for Methylene Blue Decolorization

Ting Zhang, Chunyuan Qian, and Lingyu Dong
Abstract—New simple wet-ultrasonic method was employed to synthesize akind of particle heterogeneous catalyst Fe3O4/attapulgite (Fe3O4/ATP), which used attapulgite particles as catalyst carrier and Fe3O4 as active component loaded on the carrier. The catalyst is low cost and easy to prepare, and the effects of various preparing factors on its catalytic performance were investigated and discussed. The heterogeneous catalyst was characterized using SEM, FT-IR and XRD for its structure and catalysis properties. Fe3O4/ATP was used as the catalyst to decolorize high concentration (100mg/L) methylene blue (MB) in the heterogeneous Fenton system. Box-Behnken design (BBD) method was used for experimental design, data analysis and optimization. The influences of catalyst dosage, H2O2 initial concentration and pH value on MB decolorization ratios in Fe3O4/ATP/H2O2 heterogeneous Fenton system were studied. The heterogeneous catalyst Fe3O4/ATP has excellent catalytic performance and more than 99%MB decolorization were achieved under the optimum conditions. Higher decolorization ratio was obtained for recycled use of Fe3O4/ATP. Comparison experiments showed MB decolorization in Fe3O4/ATP/H2O2 system is really a catalytic process. Furthermore, Fe3O4/ATP can be easily separated from the solution and reused due to its particle form.

Index Terms—Fe3O4/attapulgite, particle catalyst, heterogeneous Fenton system, methylene blue decolorization.
