Summary: This study developed a simple carbonization method to prepare porous carbon. The carbon materials prepared at 900°C (PCMCA-900) showed a high specific surface area and pore volume, making it effective for CO2 adsorption and the removal of Congo red dye. The evaluation results suggest that this porous carbon is an ideal candidate for CO2 adsorption and dye removal.

Summary: Boehmite adsorbents with high percentage of exposed (020) facets and large specific surface area were prepared using the rotating liquid film reactor method at different rotating speeds. The adsorption behavior followed the pseudo-second-order model and Langmuir isotherm model towards Congo red, with the best performance shown in the B-1500 sample. The alginate-assisted moulding method for boehmite pellets showed promising applications for CR removal in water.

Summary: Developing a novel chitosan porous microsphere with outstanding adsorption performance and magnetic separation function is significant for recycling and purification in wastewater treatment applications. Magnetic chitosan/GO@Fe3O4 porous microspheres (MCMS) were fabricated by incorporating magnetic graphene oxide nanocomposite (MGN), which significantly improved the adsorption performance of MCMS microspheres. MCMS showed excellent magnetic separation performance and enhanced thermal stability.

Summary: The study evaluated the adsorption behavior and mechanisms of surface modified activated carbon with bacteria. Results showed that modified activated carbon had high adsorption efficiency under weakly acidic pH, with adsorption capacity increasing with temperature. The adsorption of Congo red by bacteria surface modified activated carbon fitted well with the Langmuir's model, and the process was endothermic with physical adsorption as the main driving force.

Summary: The excessive presence of synthetic dyestuffs in aquatic environments can lead to ecological and health issues that are harmful to sustainable development. Adsorption is considered an effective method for removing dye pollutants from water due to its efficiency, cost-effectiveness, ease of operation, and lack of secondary pollution. Among various dyes, Congo red is a commonly used azo dye. Nickel-based materials have been extensively studied for Congo red adsorption due to their diverse morphology, large specific surface area, and strong affinity towards Congo red. However, the challenge remains in creating nickel-based adsorbents with high efficiency, stability, and recyclability for practical applications.

Summary: Organic dyes have harmful effects on water environment. A metal-organic framework [NH2-MIL-101(Fe)] with AgCl nanoparticles was synthesized and used for both adsorption and degradation of Congo red. The adsorption kinetics followed a secondary adsorption kinetics equation with a maximum capacity of 248.4 mg·g-1. The degradation of Congo red followed pseudo-first-order kinetics with a degradation rate of 0.077 min-1, and complete degradation was achieved within 18 minutes. AgCl/NH2-MIL-101(Fe) shows potential for dye removal from wastewater.

Summary: By developing carbon-based MgAlF5·1.5H(2)O nanocomposites through single-step HF etching, enhanced adsorption capacity for Congo Red wastewater was achieved, with significantly higher efficiency compared to porous carbon and carbon-coated palygorskite sorbents. The newly developed adsorbents exhibit super high adsorption capacity, low cost, and pH-independent characteristics, meeting the requirements for wastewater dye removal, especially under emergency circumstances.
