Development Of Pesticide Sensing Polyaniline Electrode Through Detection Of Alachlor By Cyclic Voltammetry, Todd M. Conner

Honors College

This research project was done to develop a chemical sensor for detection of a specific pesticide, a chlorinated herbicide called alachlor. Alachlor is an herbicide used to kill broadleaf weeds that grow mainly in corn, peanuts, and soybeans. The purpose of this project was to develop an environmentally friendly sensor in the form of an electrode that will be able to detect alachlor in aqueous samples. The way this was done was by using an electrochemical instrumentation technique called cyclic voltammetry. Polyaniline, a conducting polymer, was grown on a platinum substrate and the resulting electrode was cycled in various concentrations …
