Description This paper deals with application of CdTe nanoparticles for analytical determination of Cu(II) and Pb(II) ions by means of laser-induced luminescence spectroscopy. The analytical procedure was optimized for experimental conditions (pH, concentration of nanoparticles and analyte) and then it was utilized for simultaneous determination of both metal ions in water samples. The proposed method is simple and fast and it can be employed for analysis out of lab.
