本文报道了在紫外光照射下，由于金属离子在电极表面的光沉积作用，Ti/TiO 2电极对痕量重金属离子（如Cu ~（2+）、Pb ~（2+）和Cd ~（2+））的测定灵敏度显著提高。Ti/TiO 2电极对重金属离子的灵敏度可以选择性地提高，这是由于重金属离子的电位与TiO 2导带位置相匹配。(C)2015年由Elsevier B. V.出版
Here we reported that UV light irradiation can significantly enhance sensitivity of Ti/TiO2 electrode for determination of trace heavy metal ions (such as Cu2+, Pb2+ and Cd2+) owing to the photodeposition of metal ions on the surface of electrodes. The sensitivity of heavy metal ions can be selectively enhanced over the Ti/TiO2 electrode, which is attributed to matching between potential of heavy metal ions and the position of the conduction band of TiO2.
