A series of reactions between cationic ions and nickel tetrasulfonated phthalocyanine (nickel 4,4’,4’,4’-tetrasulfophthalocyanine, NiS 4 Pc) were performed and demonstrated that water-soluble NiS 4 Pc can complex with Pb 2+ to form an insoluble compound, many acid anions can dissolve this compound. However, the presence of acidic materials (acid inhibitors) can inhibit the dissolution of this compound by acid anions. Screening of acid inhibitors led to an important finding. In the presence of a low concentration of citric acid, the precipitate dissolution by most anions was completely or significantly inhibited; only 5 3 10 P O − could still dissolve the precipitate compound, NiS 4 Pc-Pb(II), to release NiS 4 Pc. The solution phase shows the characteristic color and absorption spectroscopy of NiS 4 Pc-Pb(II), thus providing a specific optical probe for 5 3 10 P O − . In addition, the color and absorption intensity of the solution remained stable for a long time (more than three months), indicating significant stability of the optical probe. Based on this finding, a new spectrophotometric technique has been established for detecting and quantifying aqueous

Achieving sensitive and selective detection of Bacillus anthracis is of great significance for preventing anthrax infection. This work constructs a Luminol-Tb fluorescent complex based on phosphate (Pi) regulation (Luminol-Tb-Pi) for the rapid, sensitive, and visual detection of anthrax bio-marker (2,6-pyridyldicarboxylic acid, DPA). U nder the regulation of Pi, with Luminol as the organic ligand and Tb 3+ as the central ion, DPA can significantly enhance the characteristic fluorescence of Tb 3+ and cause quenching of Luminol. DPA acts as the antenna ligand of Tb 3+ to sensitize its luminescence, and Pi enhances the sensitization of DPA by reducing the distan ce between DPA and Tb 3+ . In addition, the coordination of Pi with Tb 3+ can reduce the quenching effect by water molecules, further enhancing Tb 3+ fluorescence. Due to the competitive binding between DPA and Tb 3+ , the coordination between Luminol and Tb 3+ i s weakened, and some Luminol become free, leading to their fluorescence quenching. Based on the dual fluorescence signal, the ratiometric detection of DPA is achieved with a quantitative range of 0.2 ~ 45 μM. In addition, the visual dete c-tion of DPA can be achieved based on the fluorescence color change of this sensing system. The sensing method developed is simple, low cost, and possesses potential in actual applications.
