摘要：
The electro-oxidation processes of sulfide at Ti/RuO2 anode in alkaline solution are investigated. The experiment results indicated that the electro-oxidation process of sulfide is irreversible, and the control step is mass diffusion. The final electro-oxidation product is mainly SO42- (95.8%), while S2O32- + SO32- is 3% and sulfur is 1.2% under the experiment conditions (0.023M Na2S, 25mA.cm(-2), pH 13, 20 degrees C). The SEM results show that the sulfur deposit on the surface of anode with porous structure, and the XRD results confirm that the sulfur is alpha-S-8. Michaelis-Menten equation can be used to describe the electro-oxidation process, and the values of V-max (0.011 mol.L-1. h(-1)) and K-m (0.010 mol.L-1. h(-1)) are put forward.
