Summary: This study evaluated the equilibrium and kinetics properties of CO2 adsorption on two RSS-derived AC samples. The Freundlich model accurately described the experimental results, indicating a heterogeneous phase for the adsorption process. The pseudo-second order model was found to be the most suitable for both blank and IL-functionalized AC.

Summary: This study examined the recovery of Cu2+ ions using activated carbon obtained from industrial polyvinyl chloride waste. The raw material was chemically treated and activated carbon was obtained through pyrolysis. The surface properties of the adsorbent were characterized using XRD, SEM, and FTIR. The adsorption experiments showed that pH, solid/liquid ratio, concentration, and temperature had an effect on the removal effectiveness. By using Box-Behnken design, the parameters were optimized. The results showed a removal percentage of 98% and a maximum adsorption capacity of 145.63 mg/g, following a pseudo-second order kinetic model.

Summary: A highly-efficient sorbent, Cu-In spinel-type sulfides, was synthesized through a hydrothermal synthesis and showed excellent mercury removal performance at low temperatures. The mercury removal efficiency significantly improved as the Cu proportion increased, with CuInS2 sorbent reaching 99.6% removal efficiency at 125 degrees C. The study demonstrated a potential for applying CuxIn2-xS2 sorbents to capture gaseous mercury at low temperature.

Summary: In this study, a volumetric system was used to evaluate the adsorption performance of carbon-based adsorbents for oxygen, nitrogen, and carbon dioxide gases. The effects of ZnCl2 addition and heat treatment temperature on the adsorptive capabilities were investigated. The results showed that the addition of ZnCl2 improved the adsorption capacity for oxygen. Additionally, the adsorption isotherm and kinetic models indicated that the optimal sample exhibited the highest adsorption capacity for oxygen compared to nitrogen and carbon dioxide.

Summary: In this study, AC obtained from apple peel was used to remove NR from aqueous solutions. The AC was characterized using BET, FTIR, XRD, and SEM/EDX analyses. Isotherm, kinetic, and thermodynamic parameters were determined and the Langmuir isotherm and PSO kinetic models showed the best fit to the experimental data. The removal percentage of NR dye reached up to 87.20% at 318 K. The research demonstrated the effectiveness of biomass-derived AC for wastewater treatment through adsorption technique.

Summary: This study explored the pyrolysis behaviors and mechanisms of different monosaccharides, including arabinose, galactose, galacturonic acid, and glucuronic acid. The roles of structural differences in these monosaccharides were analyzed, and it was found that glucuronic acid undergoes a special C-C bond breaking reaction during pyrolysis. The findings provide a deep understanding of the pyrolysis chemistry of hemicellulose and the role of different branches.
