【Abstract】 The electrochemical behavior of riboflavin on the multiwalled carbon nanotube modified electrode was investigated by cyclic votammetry.The results indicated that and the production by reduction reaction can be strongly adsorbed on the modified electrode.One pair of prewaves the multiwalled carbon nanotube modified electaode had an obvious electaocatalytic effect on riboflavinand one pair of two-electron redox waves were exhibited at low concentration and low scan rates.The peak current was proportional to the concentration of riboflavin over the concentration range from 1.0×10^-5 to 1.0×10^-4mol/L with correlation coefficient of 0.99757.更多还原
