摘要：

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 x 10(-7) Mol l(-1) and a linear range of 5 x 10(-7)-1 x 10(-4) Mol l(-1). The possible interference from several common ions was tested. The proposed method was successfully applied in the detection of nitrite in real samples. (c) 2005 Elsevier B.V. All rights reserved.
