DEVELOPMENT OF APPLE TISSUE AND ACID TREATED MULTI WALLED CARBON NANOTUBE BASED AMPEROMETRIC BIOSENSOR FOR PHENOL DETECTION

The fabrication of acid functionalized multi-walled carbon nanotube (fMWCNT) combined apple tissue based amperometric biosensor through a cross-linking agent-free approach has been presented for the phenol detection in this study. Apple entrapped fMWCNT-glassy paste composite was employed as natural polyphenol oxidase source enzymatic oxidation and consumption dissolved oxygen monitored via chronoamperometry response. effect experimental parameters (e.g. working potential, pH amount) were examined to obtain optimum measurement conditions. Under optimized conditions, responses linearly increased range 10-200 µM limit calculated 3.26 (n=3). utilized tap water samples by serving satisfying recovery values.
