Energized dispersive guided extraction (EDGE): a promising tool for analytical chemistry applications.

Analytical chemistry demands precise sample preparation methods to ensure accurate qualitative and quantitative determinations, especially those capable of clean-up and preconcentration of target analytes. Extraction plays a crucial role in enhancing the selectivity and sensitivity of analytical procedures. Thus, Energized Dispersive Guided Extraction (EDGE) has emerged as an innovative alternative to traditional methods, such as Soxhlet, maceration, and percolation, as well as modern techniques like Accelerated Solvent Extraction (ASE), Supercritical Fluid Extraction (SFE), and Microwave or Ultrasound Assisted Extraction (MAE and UAE).

Emerging carbonaceous material based on residual grape seed applied in selective and sensitive electrochemical detection of fenamiphos.

Fenamiphos (FNP) is a pesticide applied for soil pest control, particularly nematodes, and sucking insects, including aphids and thrips. Despite its use being banned in several countries due to its highly toxic nature for living beings, including mammals, because of its acetylcholine-inhibiting action, it is still marketed for use in agriculture. Therefore, a carbon paste electrode modified with residual grape seed biochar (bSU), served as an electrochemical sensor (E-bSU) for the quantification of fenamiphos in grape juice, tap water, and river water samples.

Simultaneous determination of carbendazim and carbaryl pesticides in water bodies samples using a new voltammetric sensor based on Moringa oleifera biochar.

For the first time, a modified electrochemical sensor based on carbon paste was developed using biochar derived from the husks of Moringa oleifera pods to detect successfully and simultaneously carbendazim (CBZ) and carbaryl (CBR) pesticides. Biochar was obtained via pyrolysis at 400 °C, which required no additional activation or modification processes. The incorporation of the biochar modifier enabled the preconcentration of both pesticides under open potential circuit conditions, resulting in a significant enhancement in sensitivity compared to bare electrode.
