“…The maximum allowable cyanide in drinking water is 1.9 μM. [56,57] Therefore, developing effective detection methods for selectively monitoring of cyanide ions is crucially important. [58,59] Considering the above facts, Choi's team developed the turn-on fluorescent probe 20 for the detection of cyanide ions based on the naphthalimide-benzothiazole group (Figure 10).…”

Naphthalimide derivatives are attracting increasing attention as fluorescent probes due to their excellent modifiability and photophysical properties. Their large, rigid coplanar structures and conjugated systems enable easy generation of fluorescence. The imide units and bromonaphthalene functionality offer facile and concise modification pathways in preparing amenable probes for different metal cations, anions, small molecules, and organelles. Therefore, naphthalimide probes have great potential for application in research fields, such as analytical chemistry, cell biology, and clinical diagnosis.

“…[14][15][16]. Among these, electrochemical techniques appear to be more suitable due to their fast response, low cost, high selectivity, and sensitivity [7,[17][18][19][20]. Electrochemical detection relies on electrode supporting materials, such as glassy carbon (GC), which is extensively used due to its ability to adsorb carbonaceous materials like graphene oxide [20], multi-walled carbon nanotubes [18,22], and hierarchical porous carbon [19,20].…”

Heavy metal‐containing industrial effluent streams from electroplating and metalworking industries represent a major environmental issue. They contain metal cyanide complexes ([Ni(CN)4]2− and [Cu(CN)3]2−) referred to as weak acid dissociable cyanide (CN‐WAD), which require continuous in situ monitoring. In this scenario, a glassy carbon (GC) electrode superficially decorated with 9,10‐phenanthroquinone (FNQ) is manufactured and employed for the simultaneous electrochemical monitoring of cyanide WAD complexes. The interaction between GC and FNQ was characterized by Raman and electrochemical impedance spectroscopies, cyclic voltammetry, and chronocoulometry. The electrochemical evaluation was conducted by differential pulse voltammetry (DPV) and CV. The GC/FNQ electrochemical sensor simultaneously detected cyanide complexes with an average linear range of 9–93 μmol L−1, and a detection limit of 0.15±0.04 μmol L−1 and 1.2±0.6 μmol L−1 for [Ni(CN)4]2− and [Cu(CN)3]2−, respectively. The sensor demonstrated remarkable selectivity in the presence of multiple interfering species with a percentage variation range of 89.2–109.4 %. Moreover, a computational DFT study provided valuable insights into the electrode/electrolyte interface. Finally, the developed sensor was applied for the electrochemical detection of WAD cyanide in river water samples.

Heavy metal-containing industrial effluent streams from electroplating and metalworking industries represent a major environmental issue. They contain metal cyanide complexes ([Ni(CN)4]2- and [Cu(CN)3]2-) referred to as weak acid dissociable cyanide (CN-WAD), which require continuous in situ monitoring. In this scenario, a glassy carbon (GC) electrode superficially decorated with 9,10-phenanthroquinone (FNQ) is manufactured and employed for the simultaneous electrochemical monitoring of cyanide WAD complexes. The interaction between GC and FNQ was characterized by Raman and electrochemical impedance spectroscopies, cyclic voltammetry, and chronocoulometry. The electrochemical evaluation was conducted by differential pulse voltammetry (DPV) and CV. The GC/FNQ electrochemical sensor simultaneously detected cyanide complexes with an average linear range of 9.09 - 92.8 μmol L-1, and a detection limit of 1.47 ± 0.11 μmol L-1 and 1.2 ± 0.6 μmol L-1 for [Ni(CN)4]2- and [Cu(CN)3]2-, respectively. The sensor demonstrated remarkable selectivity in the presence of multiple interfering species with a percentage variation range of 89.2-109.4%. Moreover, a computational DFT study provided valuable insights into the electrode/electrolyte interface. Finally, the developed sensor was applied for the electrochemical detection of WAD cyanide in river water samples.
