“…Most of these strategies, however, require cumbersome preparative procedures of a sensing molecule and/or unwieldy sample preparations or necessitate sophisticated instrumentation. Further, it has been reported that the anions such as SCN À , S 2À , I À , SO 2À 3 , NO À 2 , NO À 3 , AcO À , H 2 PO À 4 and halides particularly F À tend to mask the detection of cyanide [10,11,[14][15][16][17][18][19], which has been carried out either in organic medium or organic/water medium, limiting their use in real-life situations. With a vast variety of chemical, operational and executive variations available with the chemists, in the area of chemosensors, especially for sensing of cyanide, the realistic need seems to be finding interference-free chemosensors which can work in aqueous medium [20,21] and at the same time should be cost-effective and capable of expeditious implementation.…”

“…Numerous methods for the detection of micromolar amounts of cyanide relying on the principles of chemiluminescence [7,8], electrochemistry [9], spectroscopic and spectrofluorimetric techniques [10][11][12], biosensors [13] and flow injection analysis [14] based on the rationale of hydrogen bonding interactions, metal coordination, or the formation of covalent bonds have been described. Most of these strategies, however, require cumbersome preparative procedures of a sensing molecule and/or unwieldy sample preparations or necessitate sophisticated instrumentation.…”

“…Hefter and Longmore [90] used a cyanide ISE in continuous monitoring of cyanide in seawater, and demonstrated that the well documented chloride electrode interference may be corrected when the chloride selectivity coefficient and concentration are known. Alternatively, Neshkova and co-workers [91,92] explored a new generation of electrodeposited thin film silver chalcogenide cyanide ISEs as FIA detectors for the analysis of natural waters, noting that these electrodes possess sufficient sensitivity for the analysis of environmental samples and that the electrodeposition method used in the preparation of the sensor lends itself to in-situ electrode regeneration; an important attribute when these electrodes are used in longterm monitoring in field instrumentation providing a possible source of electrode fouling during continuous electrode exposure to complex media such as seawater. In essence, the novel approach of Neshkova and co-workers [91,92] is a promising method that is expected to gain widespread use in future environmental research.…”

This review will illustrate how it is possible to develop ion-selective electrode (ISE) methodologies that meet the stringent requirements (i.e., high selectivities and very low detection limits) for the analysis of important analytes in the environment, and will present a variety of examples on the application of ISEs in environmental analysis. Despite the experimental biases that have limited the analytical performance of ISEs through apparently high detection limits and modest selectivities, there has been a plethora of research in the application of ISEs in the monitoring of environmentally important trace metals and anions in natural waters and soils. Most popular has been the analysis of free metals in natural waters, as this parameter is known to be a master variable in the uptake and toxicology of trace metals on aquatic biota reflecting the bioavailability of trace metals in the environment. Furthermore, as copper is a major trace metal in coastal waters due to its extensive use in antifouling paints on sea vessels and structures, there are many reports in the literature on the use of the copper ISE in assays of either free copper or the copper complexing capacity of natural waters and soil peats. Moreover, there have been a variety of studies showing a strong correlation between free copper levels and the toxicity of copper on a variety of marine and fresh water organisms. Nevertheless, there are numerous reports in the literature that have used ISEs to monitor important anions such as fluoride, phosphate, sulfate, nitrate, nitrite, chloride, cyanide, etc., as well as other important cations such as ammonium and chromium(VI) in waste and natural waters. In conclusion, this review will present new and interesting perspectives on the application of ISEs in environmental analysis using approaches such as real-time remote monitoring of water quality, shipboard monitoring of environmentally important analytes using flow analysis instrumentation, the use of robust all-solid-state ISEs in submersible instruments for long-term deployment in the field, and innovative analytical approaches such as backside calibration and switchtrodes that avoid standard addition analysis and the concomitant perturbation in analyte speciation in natural samples.

Benzoquinone–imidazole hybrids as selective colorimetric sensors for cyanide in aqueous, solid and gas phases

Five new chemosensors (R1-R5), possessing benzoquinone as signaling unit and imidazole as H-bond donor unit, for cyanide sensing have been rationally designed, synthesized and characterized by NMR and mass spectroscopy. The structure of R5 was confirmed by single crystal XRD studies. These receptors exhibited prominent visual colour change toward cyanide ion over other common anions in aqueous HEPES buffer-DMF (9:1 v/v) medium. The complexation of receptor-CNhas been addressed by UV-Vis, fluorescence and 1 H NMR spectra and was supported by electrochemical and DFT studies. The mechanism of sensing involves formation of H-bond between imidazole N-H and CNion. The stoichiometry of the receptor-CNcomplexes was found to be 1:2 (receptor-CN -) and the detection limit was observed to be in the range of 1.1-3 nM. The test strips based on R5 were fabricated, which could act as convenient and efficient CNtest kits. Notably, the novelty of the present investigation is that the receptor R5 selectively senses CNion in solid, aqueous and gas phases i.e. 'a complete receptor'.
