This work presents a new method for the simple and inexpensive determination of atrazine. The method is based on the use of a novel, partially disposable, plant tissue bioelectrode, which is sensitive to a variety of mono- and polyphenols. The biosensor is obtained by coupling a thin slice of potato (Solanum tuberosum) tissue, which contains high levels of the enzyme polyphenoloxidase (PPO), to a commercial O2-selective Clark electrode. The concentration of atrazine in aqueous samples can be determined thanks to its inhibitory power toward the catalytic activity of PPO. The low cost of this device and its good analytical performance suggest its application in the field of environmental analysis, especially in the continuous monitoring of atrazine in risk areas.

Abstract

This work presents a new method for the simple and inexpensive determination of atrazine. The method is based on the use of a novel, partially disposable, plant tissue bioelectrode, which is sensitive to a variety of mono- and polyphenols. The biosensor is obtained by coupling a thin slice of potato (Solanum tuberosum) tissue, which contains high levels of the enzyme polyphenoloxidase (PPO), to a commercial O2-selective Clark electrode. The concentration of atrazine in aqueous samples can be determined thanks to its inhibitory power toward the catalytic activity of PPO. The low cost of this device and its good analytical performance suggest its application in the field of environmental analysis, especially in the continuous monitoring of atrazine in risk areas.
