Study of the voltammetric behaviour of maleic hydrazide and its determination at a hanging mercury drop electrode

Voltammetric determination of phytoinhibitor maleic hydrazide using PEDOT:PSS composite electrode

“…The sensors reported in the literature [16][17][18][19] due to wider linear range, lower limit of detection and higher sensitivity. This is mainly because that the prepared electrode combined excellent performance of different components.…”

“…The nature of the electroreduction and/or oxidation could offer information about the species predominating in the solution if the conversion of one tautomeric form into another was not extremely fast [16], thus the different mechanism for the detection of MH via electrochemical reduction was proposed [16,17].…”

“…Compared with aforementioned traditional techniques, electrochemical technique is a powerful tool owing to its advantages of simple operation, cost effectiveness, fast analysis, high sensitivity, and real-time online detection. Unfortunately, only few studies have been reported for MH determination 4 using chemo/bio-sensing technology [16][17][18][19]. Shibata and Zuman reported the detection of MH by polarographic method [16].…”

“…Shibata and Zuman reported the detection of MH by polarographic method [16]. Ni et al detected MH in ware vegetable samples [17], but the MH content was too low to be quantitatively detected by voltammetric method. Moreover, future regulations and occupational health consideration severely restrict (or ban) the use of mercury as an electrode material because of the toxicity of mercury [20].…”

Development of an adsorptive catalytic stripping voltammetric method for the determination of an endocrine disruptor pesticide chlorpyrifos and its application to the wine samples

“…Pesticide residue analysis by voltammetric methods is carried out especially in commercial formulations [25][26][27], water [28][29][30][31][32][33], and soil samples [34][35][36][37][38]. To date, a few studies were reported describing voltammetric determination of pesticide residues in food sample including liquid-liquid extraction and clean-up stages prior to the analysis [29,39].…”
