Summary: A highly selective and sensitive fluorescent sensor based on rhodamine fluorophore was developed for detecting Cu2+. The sensor displayed a strong fluorescence turn-on effect upon addition of Cu2+ and could be recognized by the naked eye. The sensor also enabled quantitative analysis of Cu2+ due to the formation of a stable 1:1 metal-ligand complex in a short time, which exhibited good pH stability. Furthermore, molecular orbital and spatial structure investigations, as well as cell imaging and zebra fish experiments, demonstrated the broader application prospects in biological systems.

Summary: Improving the water solubility of natural product cellulose and using it to treat heavy metal ions is crucial. In this study, cellulose-based fluorescent probes were synthesized and effectively recognized and removed Hg2+/Hg22+ ions in water. The cellulose was modified to achieve better solubility and the resulting probes showed high solubility, enabling their application in various forms. These probes exhibited turn-on fluorescence upon the addition of Hg2+/Hg22+ ions and also acted as efficient adsorbents. The removal efficiency and adsorption capacity of the probes were promising, making them potential tools for treating polluted environments.

Summary: In this study, the adsorption mechanisms of polyethylene glycol modified MgAl-LDH for Cu(II), Pb(II), and Cd(II) were qualitatively and quantitatively investigated. The results showed that the precipitation mechanism was the main contributor, accounting for 44.20%-72.12%. The contributions of complexation, isomorphous substitution, and electrostatic attraction to the total adsorption amounts were 12.43%-37.89%, 6.35%-18.81%, and <3.5%, respectively. After modification, the contribution of precipitation increased and complexation decreased.

Summary: NiFe-LDH and NiFe/MoS2 were synthesized via a hydrothermal method to decontaminate wastewater contaminated with high concentrations of Cr(VI). The addition of MoS2 improved the conductivity, capacitance reversibility, charge efficiency, coulombic efficiency, and stability of NiFe/MoS2. The CDI process using NiFe/MoS2 and activated carbon as the anode and cathode achieved a deionization capacity of 49.71 mg/g and a removal ratio of 99.42% for Cr(VI) at 1.2 V and 20 mL/min. The Langmuir model accurately described the isothermal data, with a theoretical maximum deionization capacity of NiFe/MoS2 for Cr(VI) being 106.2 mg/g. The interaction mechanisms included electrostatic attraction, surface complexation, and reduction. These findings suggest the practical application potential of NiFe/MoS2 in Cr(VI) wastewater treatment.

Summary: The study aimed to improve the efficiency of heavy metal adsorption using biochar-based materials. A composite material (BC-LDH) was prepared by loading MgAl-layered double hydroxide (MgAl-LDH) onto coconut shell biochar (BC) for the decontamination of Pb(II) and Cu(II) in water. The BC-LDH exhibited higher removal capacities for Pb(II) and Cu(II) compared to BC and LDH. Characterization results revealed that the interaction mechanisms between BC-LDH and heavy metals included mineral precipitation, cation exchange and isomorphic replacement, electrostatic attraction, and surface complexation.

Summary: This study investigates the catalytic performance and inherent mechanism of ammonium thiomolybdate ((NH4)2Mo3S13) for activating peroxymonosulfate (PMS) in degrading organic pollutants. The (NH4)2Mo3S13/PMS system shows selective degradation of certain pollutants due to the adsorption affinities of (NH4)2Mo3S13. Surface-exposed Mo(IV) and S are identified as the main active sites for activating O2 and PMS. Singlet oxygen is found to be the crucial active species in the (NH4)2Mo3S13/PMS system.
