Fabrication of a new modified gold electrode based on gold nanoparticles and nanomagnetic Fe₃O₄/SiO₂–(CH₂)₃–SH core shell for electrochemical evaluation and determination of dinitramine herbicide in water

Abstract

A novel sensitive voltammetric method is described for the determination of dinitramine based on its electrochemical oxidation on gold electrodes modified with Fe3O4@SiO2–Si–(CH2)3–SH core shell (Au/Au–NPs–S–(CH2)3–Si–SiO2@Fe3O4).

“…A similar mechanism has been proposed for niclosamide [51] and various types of aromatic nitro compounds [52] in our previous article. Although a different mechanism for TFA and some molecules similar to TFA such as dinitramine was explained based on electrochemical oxidation of tertiary amine functional group in TFA structure involving two electrons and two protons in some previously published studies [8,53], recently one published study supported our proposed mechanism [24]. A possible redox mechanism was also given in Figure 3.…”
