Development of Diamond Composite Electrode for Anodic Oxidation of Organic Pollutants

摘要: Abstract Nano-diamond composite electrode was prepared and used as anode for anodic oxidation process organic chemicals. Electrochemical techniques such impedance cyclic voltammetry have been to characterize the diamond properties. The power of 0.8 V vs. Ag/AgCl, charge transfer rate 12.1 ohm, double layer capacitance less than 1 μF. behavior p-benzoquinone, 2-chlorophenol, phenol over were investigated by in 0.1 M H2SO4 (pH 3) solution 0.25 M Na2SO4 6.8) solution. Results marked that electro-oxidation p-benzoquinone more active 2-chlorophenol both solutions. performance during incineration 200 mg/L an aqueous pH 3 6.8 with supporting electrolyte applied current density 40 mA/cm2. showed degradation benzoquinone faster different Moreover, enhanced at high solution, on contrary clearly favored acid medium.
