Summary: An environmentally friendly hydrogel adsorbent (DEC@GEL) was successfully prepared by a simple free-radical polymerization method, exhibiting abundant functional groups and porous structures. Batch and multisystem adsorption experiments were conducted to investigate the adsorption properties of various dyes in wastewater, revealing consistent kinetics and isotherms with the pseudo-second-order and Langmuir model, respectively. The maximum adsorption capacities of the four tested dyes were higher than many reported adsorbents. Moreover, DEC@GEL demonstrated high reusability, selectivity, and potential for practical industrial applications.

Summary: A new nanocomposite, A-CNF/DT, was successfully synthesized and used for the removal of methylene blue and indigo carmine dyes from water. Langmuir and Sips isotherm models well fitted the adsorption isotherm data of methylene blue and indigo carmine onto A-CNT/DT, respectively. The experimental kinetic data showed good agreement with pseudo-first order model (for the adsorption of methylene blue) and pseudo-second order model (for the adsorption of indigo carmine) onto A-CNT/DT. Thermodynamic parameters indicated that the adsorption of methylene blue was endothermic, while the adsorption of indigo carmine was exothermic. Monte-Carlo calculation method revealed both polar and nonpolar interactions between the dye molecules and the A-CNT/DT surface. Overall, the synthesized A-CNT/DT proved to be an efficient adsorbent for the removal of dyes from aqueous solutions.

Summary: It was found that various carcinogenic dyes in water bodies are difficult to degrade due to their stability, causing extended pollution. To tackle this issue, two metal-organic framework materials (MOF 1 and MOF 2) were synthesized and characterized. Based on their structural characteristics, two cationic MOF material skeletons (MOFs I and II) were designed and obtained through calcination to remove free components. The adsorption capacity of MOF I for Congo Red was found to be 2922.8 mg g-1. The adsorption process follows the pseudo-second-order kinetic model and Freundlich isotherm model. Electrostatic interactions and hydrogen bond were identified as the main factors promoting the adsorption of Congo Red dyes on MOF I. Therefore, MOFs I and II are considered as promising adsorption materials for efficient removal of hazardous organic aromatic pollutants.

Summary: Material modification with low surface energy can achieve lower surface free energy on micro-and nano-rough structures, which is crucial for developing superhydrophobic surfaces. In this study, attapulgite (APT) was modified with alkylamine, alkylammonium salt, and stearic acid, and the interaction between low surface materials and attapulgite was explained. The results showed that the hydrophobicity of APT was significantly modified by the modifiers, and the surface free energy of the composites first decreased and then increased with increasing molecular number of low surface energy monomers.
