摘要

An amperometric sulfite biosensor was developed based on disposable screen printed electrodes (SPEs) and sulfite oxidase (SOx) enzyme. The developed biosensor shows good sensitivity (62 nA/ppm), reproducibility (RSD = 4%; n = 5) and a linear range of 15-1000ppm. The applicability of the biosensor for the analysis of sodium metabisulfite in shrimp farm samples was demonstrated successfully.
