DETERMINATION OF LEAD (II) AND OXYGEN CONTENT IN LIQUID MEDIUM ON TITANIUM DIOXIDE ELECTRODES MODIFIED WITH YTTRIUM
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...
