Preparation of Diamond Coated Electrodes and the Application to Wastewater Treatment

B-doped diamond coated electrodes were grown on silicon and graphite substrates respectively by hot filament chemical vapor deposition (HFCVD) method. Detailed researches have been done to check out the influence of the growth parameters on film structure, surface morphology as well as the electrical and electrochemical properties of CVD diamond films. The textile wastewater treatment with diamond electrodes had a remarkable execution. The simulative and actual textile wastewater treatment with B-doped diamond coated electrodes on Si substrate had a remarkable execution. After 2 hours, the COD of the simulative and actual wastewater was reduced by 82.14% and 86.28% respectively. And the chromaticity color of the simulative and actual wastewater was reduced by 99% and 60.45% respectively.
