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

✦ Synopsis
AbStIWt
A device based on the presence of polyphenol oxldase m potato (Solanum tuberosum) tissue was set up to detemune catechol The sensor IS reahzed by couphng a thm shce of potato true with a Clark electrode capable of measurmg oxygen evolution from a catechol solution In the concentration range 2 5 x 10F5-2 3 x 10v4 M there 1s perfect hnearlty between the electrode slgnal and catechol concentration m solution The high stabihty and the rehablhty and reproduclbihty of the results, tested over a penod longer than 3 months, and the sensltmty of the device towards mono-and polyphenol denvatwes, allow the apphcatlon of such a system m physlologlcal and pharmacological quality control
