Electroanalytical Determination of the Fungicides Folfet, Phosmet, and Dialifos in Grains and Soils

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