The analysis of diazinon in aqueous solutions using sensitive instrumental methods has gained importance. Investigation of the electrochemical behavior of diazinon on a Nafion(R)-coated glassy carbon electrode reveals the presence of a specific oxidation peak of analytical significance. The experimental parameters, such as pH, film thickness, pre-concentration potential, preconcentration time, and square-wave voltammetric parameters were optimized. Using this method, a linear calibration curve for diazinon was obtained up to 5 muM range in pH 1 citrate buffer solution with a detection limit (SIN = 3) of 75 nM.eninfo:eu-repo/semantics/closedAccess[No Keywords]Article58656957210.1023/A:10241203203592-s2.0-0345865433Q4WOS:000183791200014Q4
