“…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).…”

“…chlorinated pesticides, polychlorinated biphenyls in the environment [1]. The determination of pesticides and herbicides in many environmental matrices is generally determined by SPE-LC-ESI-MS/MS [7], UPLC-MS/MS [8], HPLC [9], GC/MS [10,11] and LC-MS/MS [12] and polarographic [15,16] and voltammetric [17][18][19] methods. Recent years have seen an upsurge of interest for rapid and sensitive analyti-cal methods for the determination of chlorinated pesticides in environmental samples e.g.…”

“…water, sediment and air. A recent literature survey on the analysis of POPs has revealed little work [15][16][17] on the use of stripping voltammetry or any other electrochemical technique for the analysis of OCPs. Thus, the present manuscript reports the redox behavior of the pesticides alachlor and chlorfenvinphos at the hanging mercury drop, Pt and working electrodes in an attempt to develop a fast, simple, low cost and selective DP CSV method for their analysis in vegetables (spinach and carrot), cow cheese, tap and marine water (Red Sea and Atlantic Ocean) and sediment.…”

Based on the redox characteristics of two selected organochlorine pesticides namely alachlor (ALC) and chlorfenvinphos (CHL) in Britton-Robinson (B-R) buffer at a hanging mercury drop, Pt and Au working electrode (HMDE), a fast, simple and selective differential pulse cathodic stripping voltammetric (DP CSV) method was developed for their determination. The cathodic stripping peak currents for ALC versus concentrations was linear in the range from 7.4 10 À9 to 1.4 10 À7 mol L À1 and in the range from 2.7 10 À9 to 1.6 10 À8 mol L À1 for CHL. The method was applied for the analysis of trace concentrations of ALC and CHL in fresh-and marine water (Atlantic and Red Sea) and sediment samples and food stuffs.

The state of the art of voltammetric and amperometric methods used in the study and determination of pesticides in crops, food, phytopharmaceutical products, and environmental samples is reviewed. The main structural groups of pesticides, i.e., triazines, organophosphates, organochlorides, nitrocompounds, carbamates, thiocarbamates, sulfonylureas, and bipyridinium compounds are considered with some degradation products. The advantages, drawbacks, and trends in the development of voltammetric and amperometric methods for study and determination of pesticides in these samples are discussed.

“…Thus, development of reliable and fit for purpose methods of analysis for mixtures of pesticides with the use of simple and relatively inexpensive instrumentation is an appropriate objective. Hence, electroanalytical techniques provide an inexpensive alternative for pesticide analysis [18][19][20][21][22][23][24].…”

A very sensitive voltammetric method for the determination of an endocrine disruptor Chlorpyrifos (CP) insecticide at ng mL -1 level was described. The pesticide was accumulated at a hanging mercury drop electrode (HMDE) and a well-resolved reduction peak was observed at -1.2 V (vs. Ag/AgCl) in pH: 2.0 media containing 5% aqueous ethanol solution. A systematic investigation of the solution parameters and operational parameters which affect the stripping response were carried out with differential pulse voltammetry. With an accumulation potential of -0.5 V and an accumulation time of 60 s, the detection and quantification limits were found to be 0.14 and 0.45 ng mL -1 , respectively. The remarkable sensitivity of the method was attributed to a catalytic process as concluded from cyclic voltammetry. The degree of interference from diverse ions and some other pesticides on the differential pulse stripping signal for CP was evaluated. The method developed was adapted for wine samples. The matrix effect of red wine was eliminated by means of liquid-liquid extraction (LLE) followed by solid-phase extraction (SPE) with satisfactory recovery values. This method offers a very sensitive and inexpensive way for determining CP residues in red wines.
