Sažetak
Titanium(IV) dissolved in water solution can be successfully determined using adsorptive cathodic stripping square-wave voltammetry in the presence of the mixed ligand system acetylacetone - lumazin (2, 4-dihydoxypteridin) maintaining pH at about 6. The method is additionally very sensitive due to the possibility of variation of square-wave voltammetric parameters such as frequency and/or amplitude. The reduction peak of the titanium mixed ligand complex was detected at the potential of -1.49 V (vs. Ag/AgCl) and a limit of detection was found to be 0.4 nM with the accumulation time of 20 minutes at the potential of -1.2 V in the UV-irradiated artificial seawater. Interferences of other trace metal ions and surface-active substances were investigated as well.
