Two kinds of attapulgite(ATP)-based catalysts were prepared by incipient wetness technique (the samples were represented by Fe(III)/ATP) and mixing method(the samples were represented by Fe2O3/ATP) separately. Their heterogeneous Fenton-like reactions were investigated for the degradation of Sodium dodecyl benzene sulfonate(SDBS) and contrasted with Fe2O3/H2O2 system. The physicochemical characteristics of the two synthesized samples were evaluated by various techniques such as XRD, SEM, FT-IR. Compared with the Fe2O3 catalyst, the two new ATP-based catalysts exhibited a higher activity and stability in SDBS mineralization. Fe (III)/ATP and Fe2O3/ATP had high catalytic reactivity at a wider pH range and repeating usage. Furthermore, an enhancement of H2O2 utilization ratio was also achieved. When introducing ATP to Fe2O3, the degradation ratios of the catalysts were greatly enhanced because ATP had excellent assistant catalytic ability.
