Photoelectrochemical Degradation of Cyanuric Acid in TiO2 Suspension

摘要：

Photoelectrochemical degradation of cyanuric acid occurred when the applied potential exceeded 2 V by using Ti electrodes and TiO2 suspension in 0.3 M NaCl solution.The removal increased drastically when the applied potential was more than 5 V.The addition of HCO3- ion could accelerate photoelectrochemical degradation of cyanuric acid.An optimum removal of 85％ was achieved when HCO3- ion concentration increased to 0.05 M.Further increase of HCO3- ion led to the decrease of removal,due to consumption of hydroxyl radicals and other oxidizing species by excessive bicarbonate.Photocatalytic oxidation had no capacity on degrading cyanuric acid whether in NaHCO3 aqueous solution or in the solution containing both Cl- and HCO3- ions.
