Abstract

This study focused on electrolysis of refractory malachite green waste water with three-dimensional electrode. In this research, high-purity graphite was used as the cathode, titanium-plating metal mesh as the anode, while coal column, coconut shell granular activated carbon and catalytic Titanium dioxide (TiO2) modified activated carbon as particle electrode, respectively. The electrolytic condition was set as follows: pH=6, the voltage of 8 v, an aeration rate of 20 L/h, an electrolyte concentration of 0.1 mol/L, an electrolysis time of 2 h, and the highest chemical oxygen demand (COD) degradation rate of malachite green was up to 99%. That TiO2 modified activated carbon served as particle electrode can increase the degradation effect and the current efficiency. Ultraviolet (UV) analysis showed that the structure of malachite green was altered to achieve an effective degradation during the electrolysis process with three-dimensional electrode.
