An Electroanalytical Sensor for the Detection of Gramoxone (Paraquat)

ABSTRACT

Glassy Carbon Electrodes coated with stearic acid provide an amperometric sensor for detection of paraquat, the active ingredient of the herbicide Gramoxone. The linear dynamic range of the sensor for Paraquat is 1.02 × 10^?3 mol dm^?3 to 1.02 × 10^?2 mol dm^?3 with the minimum detection limit 6.37 × 10^?4 mol dm^?3.
