| 英文摘要 | The study focused on the proposal and experimental validation of an combined photoelectrocatalytic principle for chemical oxygen demand determination (combined PeCOD, PeCOD-combined), which was functionally comprised of photon-efficient thin-film photochemical, photocarrier-efficient electrochemical and conventional bulk-phase photochemical digestion types in one single photodigestion process. The combined PeCOD technology was proposed mainly on the basis of the significantly informative work of existing photoelectrocatalytic COD (thin-layer PeCOD, PeCOD-thin), and could realize the three different digestion types on one single rotating photoanode. The three important operation conditions of rotating speed, applied bias and pH value were investigated and optimized, and a wide analytical linear range of 2.7-11 500 mg/L was consequently obtained during an approximately 5-110 min determination period, and a real sample analysis further validated the practical feasibility of the proposed PeCOD-combined. In PeCOD-combined the main organics digestion and signal generation occurred via PeCOD-thin due to efficient UV utilization and excellent photodigestion activity. |
