Overview
Godja et al. (2025) develop a screen-printed gold electrode-based electrochemical method for nickel(II) (Ni2+) detection in choline chloride-ethylene glycol (ChCl-EG) deep eutectic solvent medium. The study focuses on the electrochemical behavior of Ni2+ in this novel solvent medium rather than directly on food or water sample analysis.
Key numbers
LOD: 1.6 µM in ChCl-EG deep eutectic solvent, equivalent to approximately 94 µg/L (94 ppb) under the measurement conditions. This LOD is in the ChCl-EG medium, not in food or water matrices, limiting direct comparability to food analytical needs.
Methods (brief)
Screen-printed gold electrode. Differential pulse voltammetry or stripping voltammetry. ChCl-EG deep eutectic solvent electrolyte — not a food or environmental water matrix. The paper explores fundamental electrochemistry of Ni in non-aqueous solvents rather than practical food analysis.
Implications
Testing: LOD in deep eutectic solvent medium is not directly translatable to food matrix applications. Nickel (Ni) is an HMT&C analyte; analytical method development for Ni is relevant to the testing wiki pages, but this paper’s contribution is to fundamental electrochemistry rather than validated food method development.
