Abstract
The present disclosure discloses a chemical oxygen demand detection apparatus. In the apparatus, a working electrode, which is included TiO2 nanotube arrays electrode between 1800-2500 nm in length, is excited the photoelectrocatalysis reaction thereon by a single wavelength UV-LED module and an electrochemical analysis module. A fixing holder is configured to fix a three-electrode module and the UV-LED module to immerse in sample. An electrochemical analysis module, which electrical connect to the three-electrode module, is configured to receive a time-dependent current signal and integrates time-dependent current signal to get total electric charge, and generates a detecting result to indicate chemical oxygen demand value of sample.
