The effect of reaction conditions including Fe²⁺, H₂O₂ dosages and the initial concentration of Rhodamine B(RB) solution were discussed on the Fenton degradation of RB. And focusing on the influence of the presence or absence of carboxylic organics, such as oxalic acid, pyruvic acid, ascorbic acid, and humic acid on the Fenton degradation of RB under irradiation of Xe lamp. The results implicated that more than 96% removal of RB was achieved under optimal reaction conditions of pH 3.0, 0.25 mmol/L of Fe²⁺, 2.5 mmol/L of H₂O₂ and 10 mg/L of the initial concentration of RB solution after 30 min. The Fenton reaction was promoted under irradiation. The Fenton degradation of RB was completely blocked in the dark in the presence of carboxylic organics. However, it was promoted in the presence of oxalic acid, pyruvic acid and inhibited in the presence of ascorbic acid, and humic acid under irradiation, which can be attributed to the different structures of these carboxylic organics.
