Green electrochemical sensors based on boron-doped diamond and silver amalgam for sensitive voltammetric determination of herbicide metamitron

Popis výsledku v původním jazyce

Novel sensitive voltammetric methods for determination of herbicide metamitron were developed using polished and mercury meniscus-modi?ed silver solid amalgam electrode (p-, m-AgSAE) and boron-doped diamond electrode (BDDE). It was found that metamitronyields one analytically utilizable reduction (AgSAEs) and one oxidation (BDDE) signal. All three tested working electrodes connected to different voltammetric techniques were found to be appropriate for the analysis of the herbicide. The optimum conditions for detamitron determination were ascertained in Britton-Robinson buffer solution of pH 2.0 (m-AgSAE, BDDE) and in 0.05 mol dm-3 H2SO4 (p-AgSAE), respectively, with the limits of detection 3.6 9 10-8 mol dm-3 (m-AgSAE), 1.0 9 10-7 mol dm-3 (p-AgSAE),and 1.2 9 10-6 mol dm-3 (BDDE). Calculated values of relative standard deviations of repeated determinations (n = 5) in various concentration levels of metamitron did not exceed 5 % for either of the tested electrodes. Finally, practical
