    • 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.
    • 本公开公开了一种化学需氧量检测装置。 在该装置中,包括长度在1800-2500nm之间的TiO 2纳米管阵列电极的工作电极被单波长UV-LED模块和电化学分析模块激发其上的光电催化反应。 固定保持器构造成将三电极模块和UV-LED模块固定在样品中。 电气连接到三电极模块的电化学分析模块被配置为接收时间相关的电流信号,并且对时间相关的电流信号进行积分以获得总电荷,并产生检测结果以指示化学需氧量 样品。
