“…In soil and lake water samples, metals from an electrode shaped with multiwall carbon nanotubes and N,N′-di(salicylaldehyde)-1,2diaminobenzene (BSD) (BSD/MWCNTs) were detected in a 0.1 M NaNO3 solution. This technique exhibited high sensitivity, stability and reproducibility and the detection limits were low, 0.3 nM for Pb and 0.6 nM for Hg [75].…”

Heavy metals represent a class of chemical elements that includes metalloids, bases and transition metals, lanthanides and actinides. They are distinguished for their toxicity in small concentrations and for their negative effects on the environment and human health. They are present in various samples, mainly in water, industrial waste and food. The determination of heavy metals is carried out mainly by analytical methods, using spectroscopy, spectrometry and electroanalysis, while studies are being carried out for the development of new and faster methodologies and techniques for their analysis, with particular emphasis on voltammetry. This review deals with the determination of heavy metals mainly in environmental samples (water) using voltammetry. In particular, the methods of their determination are evaluated in terms of sensitivity, selectivity and applicability.

One of the most effective oral antipyretics and analgesics, ibuprofen (IBP) is a primary ingredient in hospital wastewater because it is widely used to treat both acute and chronic pain. It is important to detect its concentration in the wastewater. Bio-electrochemical sensor is a promising detection method due to its durability and accuracy. Schiffbase is an advanced electrode materials for bio-electrochemical sensor. Which able to detect (IBP) concentration in wastewater.2,3dihydroxy-N'1-((E)-2-hydroxybenzylidene)-N'4-((Z)-2-hydroxybenzylidene (Schiffbase) materials have been synthesized and characterized.IR spectroscopy data identified (OH/H2O), ʋ (H-bonding), ʋ (C = O), ʋ (COH), ʋ (C = N) function groups. The SEM images of Schiff base presented needle-like shape with regular morphology. Electrochemical electrode have been fabricated from Schiffbase materials. IBP detected electrochemically by CV, DPV, and EIS methods, sensing rate of (2E−7 A/mgL−1) with coefficient of determination was (R2 = 0.999), into two steps sensing mechanism, which correspond to the ion diffusion process, respectively. Schiffbase electrodes shows superior sensitivity for low concentration of IBP (~ 2 mg/L). Sensing mechanism proposed upon electrochemical results.
