Amperometric quantification of the pesticide ziram at boron doped diamond electrodes using flow injection analysis

[Display omitted] •Ziram is determined based on oxidation.•Flow injection analysis was used for ziram quantification.•Amperometric detection at boron doped diamond electrode was used.•High sensitivity and good selectivity are obtained. In this paper sensitive and selective quantification of the pesticide ziram exploiting its oxidation at a boron doped diamond (BDD) electrode is evaluated. The voltammetric behavior of the pesticide shows in acidic media three well-defined oxidation peaks. For quantification an analytical procedure based on flow injection analysis has been developed. Under optimized experimental conditions a linear dynamic range from 10 to 1000nM was obtained. The limit of detection (LOD) was estimated to be 2.7nM. After evaluation of effects from possible interferences, the proposed procedure was successfully applied to real samples.
