“…Both LOD and LOQ values confirmed the sensitivity of the proposed DP CSV procedure compared to most of the reported chromatographic methods e.g. SPE-LC-ESI-MS/MS [26], UPLC-MS/MS [8], HPLC [9], GC/MS [10] LC-MS/MS [12] and polarographic [13,14] and voltammetric [15][16][17] methods. The main analytical features of the proposed method were compared successfully with many of the previously published chromatographic methods ( Table 1).…”

“…Em geral, estes apresentam processo redox bem definido em meio ácido, alcalino ou neutro, que é atribuído à redução da dupla ligação carbono-carbono em cada um dos compostos e/ou à redução de íons cloreto ou grupo nitro presentes na estrutura do composto 45 . Em função das respostas eletroativas obtidas sobre mercúrio, alguns trabalhos apresentam a determinação eletroanalítica de organofosforados em cereais 54 , utilizando-se a polarografia de pulso diferencial no desenvolvimento de uma metodologia para determinação de resíduos de dicrotofós, crotoxifós e clorofenvinfós. Os resultados obtidos mostraram boa precisão e reprodutibilidade da metodologia.…”

“…3, of which some examples are dichlorvos, dicrotophos, chlorfenvinphos, crotoxyphos, are electroactive at mercury electrodes. [16,17] The electrochemical behavior of these compounds was examined over the pH range 2.0 -12.0 and for each of them was found a single well-defined wavepeak. This peak was attributed to reduction of the carbon-carbon double bound in a two-electron process.…”
