Fast Determination of Vitamin B2 Based on Molecularly Imprinted Electrochemical Sensor
Under the condition of weak acidity of pH 5.2,a sensitive vitamin B2 electrochemical sensor based on molecularly imprinted nonconducting polymer of o-aminophenol by potentiostatic polymerization in the presence of template(vitamin B2) on a glassy carbon electrode was prepared,and its performance was studied.The sensor exhibited good sensitivity and selectivity to VB2.The detection limit went down to 2.3851nM,and a linear relationship between the current incremental and the concentration was found in the range of 10~ 120nM.And the sensor could use in detection of VB2 real sample for a long time and show good reproducibility.The average recovery rate to VB2 was 98.41%.
