Embodiment 1
[0014] with TiO 2 The nanotube array film is the working electrode, Ag / AgCl is the reference electrode, and Pt is the counter electrode. In the thin-layer reactor, an amantadine organic solution with a COD concentration of 100 mg / L is injected, sodium nitrate is used as the electrolyte, and the COD concentration is 200mg / L glucose solution, apply a bias voltage, turn on the light source, the ultraviolet light wavelength of the light source is 365nm, and the light intensity is 7.9mW / cm 2 , to carry out the reaction of photocatalytic oxidation of organic matter, and monitor the change of photocurrent with the reaction time (I-t) during the photocatalytic reaction process by the electrochemical workstation. It was found that when the reaction time was 90 seconds, the photocatalytic degradation reached the end. Calculate the amount of transfer of electrons in the reaction process by integrating the I-t curve, and calculate the ratio of the reacted organic matter to the total organ...
