Application of TiO2 Modifled Boron Doped Diamond (BDD) Electrode for As(III) Determination in Natural Waters

摘要

Activated by Au nanoparticles, Boron Doped Diamond (BDD) electrode was modified electrochemically by TiC>2 and applied for As(IIl) determination in natural ground waters. The modification with T1O2 results in up to 49.7% sensitivity increase compared with the non modified electrode achieved at the maximum coverage percentage of about 73% of the BDD surface.
