▎ 摘　　要

The graphene nanosheets and carbon nanospheres mixture (GNS-CNS) was prepared by electrolyzing graphite rob in KNO3 solution under a constant current. The cationic chitosan (CS) coated Prussian blue (PB) as an efficient redox mediator could interact with the anion GNS-CNS via electrostatic interaction. The synergy effect of CS@PB nanoparticles and GNS-CNS contributed to the excellent electrochemical response towards the nitrite oxidation. The as-prepared CS@PB/GNS-CNS modified glass carbon (GC) electrode demonstrated its high sensitivity, low detection limit, short response time, and wide concentration range for the nitrite detection.
