Determination of the Pesticide in Waste Water in Karauli (Rajasthan) by Differential pulse polarography

Abstract

A Voltammetric procedure was developed for the trace determination of pesticides using Differential pulse polarography in waste water samples were described. This waste water used in irrigation of crops and vegetables in area of Karauli . Using DP polarograms of digested waste water samples in Britton Robinson buffer (BR buffer) (pH-2.87) quantities of pesticides were determined. Results obtained from the Differential pulse polarographic study of pesticide in waste water of Karauli in part per million ranges are presented in table 1.1. Which indicate that among all the pesticide Endosulphan was found in maximum concentration followed by Chlorpyrifos. Cypermethrin pesticide concentration was not observed in waste water
