摘要
Carbon nanoparticles (CNs) were successfully synthesized at room temperature, which were used to construct a novel electrochemical sensor combined with multi-walled carbon nanotubes and chitosan. The proposed CN-based sensor showed excellent electrocatalytic performance for the oxidation of nitrite and the redox of hydrogen peroxide. Based on this, new methods for the determination of nitrite and hydrogen peroxide were established. Compared with other reports, the methods were sensitive, accurate and rapid with good reproducibility, stability and certain anti-interference ability, which can be used for the measurement of nitrite and hydrogen peroxide.
