A new method for the voltammetric determination of nitrite.
A voltammetric method is presented for the determination of nitrite by use of a carbon-paste electrode chemically modified with an anion-exchanger. Because it is possible to accumulate nitrite on the electrode surface, trace nitrite concentrations down to 1 ng/ml can be determined.
