A facile and efficient strategy for photoelectrochemical detection of cadmium ions based on in situelectrodeposition of CdSe clusters on TiO ₂ nanotubes

An efficient protocol for selective and sensitive detection of Cd(2+) was first developed based on photocurrents obtained at CdSe clusters which are in situ electrodeposited on TiO(2) nanotubes with the gradual addition of Cd(2+), with theoretical and technical simplicity, and further successfully applied to an assay of Cd(2+) in tap and lake water samples.
