Abstract

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 mu mol L-1), with limit of detection (1.5 mu mol L-1), and with good reproducibility (4.1%) for nitrite analysis.
