SDBS Degradation by a Heterogeneous Fenton-Like Reaction on Three Types of Catalysts

Article Preview

Abstract:

Two kinds of attapulgite (ATP)-based catalysts (Fe (III)/ATP and Fe2O3/ATP) were prepared and their heterogeneous Fenton-like reactions were investigated for the degradation of Sodium dodecyl benzene sulfonate (SDBS) and contrast with that of Fe2O3 catalyst. Compared with the Fe2O3 catalyst, the two new ATP-based catalysts exhibited a higher activity and stability in SDBS mineralization. The effects of pH, H2O2 dosage, catalyst dosage and temperature were investigated. With incorporating ATP, the degradation ratio was more than that of Fe2O3 catalyst. And an enhancement of H2O2 utilization ratio was achieved.
