“…Hydrazone is very sensitive to heavy metals and can easily coordinate to form coordination structures, [ 15 , 16 , 17 , 18 ]. DA (dopamine) has strong functional modification ability, and catechol and amine groups could form various hydrogen bonds to adsorb target pollutants [ 19 , 20 , 21 ].…”

In this paper, functionalized sodium alginate hydrogel (FSAH) was prepared to efficiently adsorb heavy metals and dyes. Hydrazide-functionalized sodium alginate (SA) prepared hydrazone groups to selectively capture heavy metals (Pb2+, Cd2+, and Cu2+), and another functional group (dopamine grafting), serves as sites for adsorption methylene blue (MB), malachite green (MG), crystal violet (CV). Thermodynamic parameters of adsorption indicated that the adsorption process is endothermic and spontaneous. The heavy metals adsorption by FSAH was physical adsorption mainly due to ΔHθ < 40 kJ/mol, and the adsorption of cationic dyes fitted with the Langmuir models, which indicated that the monolayer adsorption is dominated by hydrogen bonds, electrostatic interactions, and π-π interactions. Moreover, the adsorption efficiency maintained above 70% after five adsorption-desorption cycles. To sum up, FSAH has great application prospect.

“…For the design of sensors for use in practical applications, the detection of ions with reusable fluorescent probes is a necessary feature [9a,15a] . After Hg 2+ was detected, EDTA (ethylenediamine tetraacetic acid) was utilized as a Hg 2+ scavenger to regenerate DPTYMH.…”

A Schiff base acylhydrazone fluorescent probe (DPTYMH) was designed and synthesized using 3‐bromo‐N,N‐diphenylaniline, 5‐formyl‐2‐thiopheneboronic acid, and 2‐hydroxybenzohydrazide. The structure was then verified by 1H NMR, 13C NMR and HR‐MS. DPTYMH exhibited positive solvent photochromic effect based on the mechanism of intra‐molecular charge transfer (ICT), and demonstrated effectiveness, high selectivity, and specificity to capture mercury ion (Hg2+). The response time and the detection limit of DPTYMH on Hg2+ was under 10 s and as low as 1.01×10−8 M, respectively. Density Functional Theory (DFT) calculation and 1H NMR were used to investigate the potential coordination mechanism. The Hg2+ level of several water samples had been effectively analyzed using DPTYMH. The molecular logic gate was also built using Hg2+ and EDTA as chemical inputs by taking use of DPTYMH′s reversibility in the presence of EDTA. Moreover, the DPTYMH was produced as test strips, which has the enormous potential to detect Hg2+ ions in the environment.

“…The uorescent probe analysis method has the advantages of rapid response, simple and convenient use, high sensitivity, and is not easy to damage biological samples. Therefore, the uorescent probe analysis method is more suitable for the detection of Trace Hg 2+ [9][10][11]. Rhodamine is an excellent uorescent probe.…”

A highly selective fluorescent probe Por-RBO for Hg2+ was designed and synthesized with Rhodamine B and porphyrin as the fluorophore. The sensor can determine the Hg2+ of a solution within the pH 5.0 to 8.0, free from interference of other metal ions. When detected in buffer solution, the fluorescence was the strongest when 5 times the concentration of Hg2+ ion was added. Calculated by fluorescence titration method, the detection limit of probe Por-RBO for Hg2+ ion was as low as 0.12µmol/L. The geometries of Por-RBO and Por-RBO- Hg2+ were optimized at the B3LYP/6-31G** level by density functional theory. The charge distribution, orbital interactions and bonding characteristics were analyzed and compared in detail to discuss the recognition mechanism and structure-fluorescence property relationships. The results of cell fluorescence imaging and CCK-8 experiments showed that the probe Por-RBO has low cytotoxicity and can be used for fluorescence distribution imaging of Hg2+in living cells.
