Abstract
This work demonstrates the possibility of using the anodic stripping voltammetry method on electrodes based on nanocrystalline thin films of yttrium-modified titanium dioxide to determine the content of lead (II) and, at the same time, oxygen in their joint presence in liquids, which is an urgent task in the development of multisensors toxic substances and oxygen in liquid media. Lead was determined by anodic potential scanning after preliminary electroconcentration of the electrode in the electrolyte solution containing Pb(II) ions; oxygen was determined by cathodic potential scanning. The influence of electroaccumulation conditions (potential and time), background electrolyte composition, and ions present on the analytical signal (AS) of lead (II) was studied. The analytical signal of lead exhibited a linear dependence on the concentration of Pb(II) ions in the electrolyte, spanning a concentration range of 0.01 to 8 mg·l-1. The maximum sensitivity of the electrodes to dissolved oxygen was (3÷6)·10-3 mg·l-1, to Pb(II) – 0.01 mg·l-1.
