sensitive, rapid, and precise determination of phenols and their derivatives is important in environmental control and protection. An amperometric principle-based biosensor, employing immobilized laccase enzyme from Trametes versicolor, is developed for the detection of disubstituted methyl and methoxy phenols (industrial effluents). Evaluation of the influence of different enzyme immobilization techniques, on nylon membrane, on the performances of laccase-based Clark-type electrodes. The analytical properties and operating stabilities of the resulting biosensors are tested with different disubstituted methyl and methoxy derivatives of phenol substrates. Co-cross-linking method is superior to the other methods of immobilization in terms of sensitivity, limit of detection, response time, and operating stability. In co-cross-linking method of immobilization, laccase is mixed with bovine serum albumin as protein-based stabilizing agent and glutaraldehyde as crosslinking agent |
