Flow injection voltammetric determination of nitrite by reduction at a glassy carbon electrode in acidic bromide or chloride media

Abstract

Nitrite can be determined by reduction at a glassy carbon electrode held at +0.3 V versus a saturated calomel electrode by flow injection voltammetry at concentrations of greater than 1 × 10–6M by direct injection of sample solution (25 µl) into an eluent 3.2 M in hydrochloric acid and 20%m/V in potassium bromide. Alternatively, the nitrite may be pre-reacted with acidic bromide before injection and determined at concentrations above 1 × 10–7M. The use of an acidic chloride medium is less satisfactory.
