N2 - A simple and sensitive photoelectrochemical sensor based on the bismuth vanadate (BiVO4) photoanode coupled to visible light excitation was developed for nitrite detection. The BiVO4
was prepared by hydrothermal methods and used as photoelectroactive
sensor. Photoexcitation with visible light allows nitrite anions to act
as highly efficient hole scavenger at low potential. The photocurrent
response increases linearly with nitrite concentration in the solution.
The proposed device operates in the range of detection (2.5 to
100.0 μmol L–1), with limit of detection (1.5 μmol L–1), and with good reproducibility (4.1%) for nitrite analysis..
