摘要：
Treatment of CI. Acid Red 17 (AR17) by heterogeneous photo-Fenton-like process was studied using calcined laterite soil as an iron source. A complete characterization was performed to explain some of the properties of the used catalyst. Comparing the processes of heterogeneous Fenton-like and photo-Fenton-like, revealed that using heterogeneous photo-Fenton-like led to the highest decolorization efficiency (94.71% at 120 mm). Experimental results indicated that the heterogeneous photo-Fenton-like process could be explained in terms of the Langmuir-Hinshelwood kinetic model. The main roles of hydroxyl radicals in degradation process were investigated by adding of various radical scavengers. (C) 2014 The Korean Society of Industrial and Engineering Chemistry.
