Abstract
A novel chitosan-carboxylated multiwall carbon nanotube modified glassy carbon electrode (MC/GCE) was developed to investigate the oxidation behavior of nitrite using cyclic voltammetry and differential pulse voltammetry modes. The electrochemical mechanism of the MC/GCE towards nitrite was discussed. The MC/GCE exhibited fast response towards nitrite with a detection limit of 1 Ã 10â7 mol lâ1 and a linear range of 5 Ã 10â7-1 Ã 10â4 mol lâ1. The possible interference from several common ions was tested. The proposed method was successfully applied in the detection of nitrite in real samples.
