“…Rrecently, numerous studies have been conducted on the impact of inorganic pollutants such as heavy metals and nitrite ions on water quality [14][15][16][17][18][19][20]. Indeed, to detect these ions, different electrochemical sensors based on modified electrodes were developed [21][22][23][24][25][26][27][28][29][30].…”

A new ternary ruthenium(III) complex with 1,3-bis(salicylideneamino) propan-2-ol and 3-picolylamine: Synthesis, characterization, density functional theory and preparation of electrochemical sensor for nitrite analysis.. Journal of Molecular Structure, Elsevier, 2014, 1076A new ternary ruthenium (III) complex with 1,3-bis (salicylideneamino) propan-2-ol and 3picolylamine: Synthesis, characterization, density functional theory and preparation of electrochemical sensor for nitrite analysis. AbstractA novel electrochemical sensor based on graphite (G) functionalised with a new ternary ruthenium (III) complex was developed and applied to detect nitrite in aqueous solution. The Ru (III) complex was synthesized using 1,3-bis(salicylideneamino) propan-2-ol polydentate Schiff base (BSAP) and 3-Picolylamine (PLA), and was characterized by elemental analysis, Fourier transform infrared spectroscopy (FT-IR), Ultraviolet-visible spectrophotometry (UV-Visible), gradient-assisted hetero nuclear single quantum coherence spectroscopy (gHSQC) and cyclic voltammetry technique. In addition, the structure of the synthesized complex was optimized using density functional theory (DFT). The results showed that the ternary Ru(III)-BSAP-PLA complex was formed and the adapted structure was an tetrahedral geometry.The electrochemical behavior of nitrite at the sensor prepared using G/Ru(III)-BSAP-PLA composite shows that the evaluated electron transfer coefficient ( 83 . 0 = α ) indicates a very significant electrocatalytic mechanism for oxidation of nitrite in the presence of the Ru(III)-BSAP-PLA complex.Comparing to other published works, the sensor developed using G/Ru(III)-BSAP-PLA exhibited low limit of detection ( LOD=1.81 µM) around pH=7. Highlights• Ternary ruthenium(III) complex with 1,3-bis(salicylideneamino) propan-2-ol polydentate base Schiff (BSAP) and 3-Picolylamine (PLA) was synthesized, characterized and the structure was optimized using density functional theory.• Graphite-Ru(III)-BSAP-PLA composite material was prepared and characterized by scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS).• Cavity microelectrode (CME) was modified with graphite-Ruthenium(III)-BSAP-PLA material.• Substantial electro catalytic effect of ruthenium(III)-BSAP-PLA complex on oxidation of nitrite was determined by using CME/G/Ru(III)-BSAP-PLA modified electrode.

“…Amperometric sensors have found the widest application as they are the most sensitive, selective, and simple measuring devices. Voltammetric measurements include linear (LSV), pulse (DPPV), and square wave (SWV) [ 108 , 109 , 110 , 111 , 112 , 113 ] modes. Better selectivity and sensitivity of sensors are observed in DPPV and SWV in comparison with LSV.…”

Analytical chemistry is now developing mainly in two areas: automation and the creation of complexes that allow, on the one hand, for simultaneously analyzing a large number of samples without the participation of an operator, and on the other, the development of portable miniature devices for personalized medicine and the monitoring of a human habitat. The sensor devices, the great majority of which are biosensors and chemical sensors, perform the role of the latter. That last line is considered in the proposed review. Attention is paid to transducers, receptors, techniques of immobilization of the receptor layer on the transducer surface, processes of signal generation and detection, and methods for increasing sensitivity and accuracy. The features of sensors based on synthetic receptors and additional components (aptamers, molecular imprinted polymers, biomimetics) are discussed. Examples of bio- and chemical sensors’ application are given. Miniaturization paths, new power supply means, and wearable and printed sensors are described. Progress in this area opens a revolutionary era in the development of methods of on-site and in-situ monitoring, that is, paving the way from the “test-tube to the smartphone”.

“…Xie et al employed a thiolated PANI-multiwalled carbon nanotubes nanocomposite for DPASV determination of Pb 2+ and Cd 2+ , with ultra low detection limits of 0.04 and 0.01 µg L -1 , respectively [28]. Another recent study reported by Djebbar et al, the humic acid-PANI composites modified cavity microelectrode was used to detect Ni 2+ and Cd 2+ via square wave voltammetry, and the limit of detection was 1.35 µg L -1 for Cd 2+ [29].…”
