Then the bioelectrochemical response of resulted sulfite biosensor was investigated at different experimental conditions. Study of  the stability of the resulted sulfite biosensor revealed that formation of a passive film on the aluminum surface causes improved stability of the electroactive films formed on the electrode surface. The bioelectrochemical response of the enzyme-modified electrode as a sulfite biosensor was investigated at different experimental conditions. The optimum pH and temperature were 8.5 and 35°C, respectively. The apparent Michaelis-Menten constant and the activation energy of the enzyme catalyzed reaction were calculated.}, keywords = {Sulfite biosensor,Aniline,Sulfite oxidase,Conducting polymer}, url = {https://ijcce.ac.ir/article_7132.html}, eprint = {https://ijcce.ac.ir/article_7132_d5c60d14f7a56824ba461c2e2ae9756a.pdf} }
