“…Due to the dissolution of the solid catalyst in acidic water to produce ferrous ions in heterogeneous system, the catalyst will inevitably increase the catalytic efficiency of MO when the pH was adjusted to below 3.0 [13], moreover Chou et al [4] also reported that the homogeneous catalysis was insignificant at pH > 4.4 when oxidizing Benzoic acid using ␥-FeOOH catalyst because the dissolved iron concentrations were very low. For enhancing catalysis, UV light was introduced into the heterogeneous Fenton system at a higher pH.…”

“…The controlling factors, such as adsorption of goethite dosage, hydrogen peroxide concentration and UV-light exposure on the oxidation of nitro aromatic explosives were investigated. The results showed that target compounds were absorbed on the surface of goethite while the oxidation was proceeding [10] . Barreiro et al investigated the oxidation of atrazine in presence of hydrogen peroxide and ferrihydrite at different concentrations and pHs [11] .…”

As other natural iron-bearing minerals, schorl could be taken as an effective iron source for degradation of organic pollutants by mineral-catalyzed Fenton-like system. In our present study, the schorl-catalyzed Fenton-like system has been successfully developed for discoloration of an active commercial dye, Rhodamine B (RhB), in an aqueous solution. Through a number of batch discoloration experiments under various conditions, it was found that the reactivity of the system increased by, respectively, increasing schorl dosage, temperature, hydrogen peroxide starting concentration and by decreasing the pH. Over 90% of discoloration ratio could be gained in less than 30 min, and nearly 70% of total organic carbon (TOC) could be removed in less than 200 min. And, the schorl catalyst could be repeatedly used at least ten times, still with high catalytic activity. Comparative studies indicated that the RhB discoloration ratios were much higher in presence of schorl and H 2 O 2 than those in presence of schorl or H 2 O 2 only, which suggested that the schorl-catalyzed Fenton-like reaction governed the RhB discoloration process. The content of Fe ion leaching in the solution was also measured using inductively coupling plasma-atomic emission spectra (ICP-AES). A mechanism proposed herein suggested that adsorption and Fenton-like reaction (heterogeneous and homogeneous) were responsible for the discoloration of RhB.schorl, Rhodamine B, discoloration, Fenton-like reaction
