Abstract

The electrochemical behavior of the fungicides folfet, phosmet, and dialifos was studied using differential pulse polarography in unversal buffers of pH 2.0 to 6.0. The cathodic peak observed for folfet, phosmet, and dialifos is attributed to the reduction of the carbonyl group, and was shown to be pH-dependent. Differential pulse polarography was used to estimate folfet, phosmet, and dialifos in agricultural formulations, grains and soil samples. Both standard addition and calibration methods were used for the analytical measurements. The lower detection limits were found to be 1.9 × 10<sup>−9</sup>, 1.72 × 10<sup>−9</sup>, and 2.12 × 10<sup>−1</sup> M, respectively.
