摘要将吡咯两亲性单体与多酚氧化酶（PPO）混合物电聚合在玻碳电极上，制成PPO酶电极，用于苯酚、3-氯苯酚和4-氯苯酚的直接安培响应。此外，检测2-氯苯酚，几个多氯苯酚和五氯苯酚进行的生物电极功能的抑制过程。从酶抑制和聚合物污染两个方面研究了生物电极的抑制机理。该系统的能力，为解决酚类污染物的混合物的生物电极响应的动力学行为的基础上，也探讨了。
Abstract A polyphenol oxidase (PPO) enzyme electrode constructed by the electropolymerization of a pyrrole amphiphilic monomer-PPO mixture, previously adsorbed on a glassy carbon electrode, is applied for the direct amperometric response of phenol, 3-chlorophenol and 4-chlorophenol. Furthermore, the detection of 2-chlorophenol, several polychlorophenols and pentachlorophenol is carried out by an inhibition process of the bioelectrode functioning. The mechanism of the bioelectrode inhibition is investigated in terms of enzymatic inhibition and polymer fouling. The capacities of this system for the resolution of mixtures of phenolic pollutants are also explored on the basis of the kinetic behavior of the bioelectrode response.
