Summary: This study investigates the use of activated carbons from virgin banana peduncle (ZR1) and iron-impregnated banana peduncle (ZR2) as adsorbents for the removal of As(V) and Cr(VI) ions from aqueous solutions. The adsorbents were characterized and the effects of various factors on metal ion adsorption were studied. The results showed that ZR1 and ZR2 had good adsorption capacities for both As(V) and Cr(VI) ions. Kinetic and thermodynamic parameters demonstrated the feasibility of the adsorption process, making ZR1 and ZR2 promising and cost-effective biosorbents for removing As(V) and Cr(VI).

Summary: Spent tyre activated carbon (STAC) shows excellent performance in dye adsorption, heavy metal removal and flue gas cleaning, outperforming commercial activated carbon (CAC) in certain applications despite lower surface areas. STAC's enhanced performance is attributed to high mesoporosity, low surface pH, and acidic surface functional groups. Steam activated STAC has comparable results to CAC in terms of surface area and pore volume, making them cleaner and sustainable alternatives to conventional products.

Summary: Activated carbon derived from waste tires exhibited higher adsorption capacities for heavy metal ions than commercial activated carbon, with electrostatic attraction and surface complexation being the dominant mechanisms. In contrast, commercial activated carbon primarily relied on ion exchange for heavy metal removal.

Summary: In this paper, the latest research trends in terms of preparation and characteristics of activated carbons for CO2 adsorption applications are comprehensively reviewed, with a special focus on future investigation paths. The reported trends are closely related to synthesis conditions to develop microporosity and surface area, which are crucial factors affecting adsorption effectiveness. Additionally, the importance of regeneration techniques is emphasized for determining material suitability for CO2 capture application. This work provides a summary and potential directions for the development of activated carbons, aiming to establish a theoretical foundation and identify relevant ongoing research scope.

Summary: In this research study, activated carbon materials were prepared from pine wood sawdust and used for the adsorptive removal of Cu(II) ions. The results showed that the activated carbon and nitrogen-modified activated carbon exhibited high sorption efficiency, with 99.9% and 99.8%, respectively, at pH 5. These findings highlight the potential of these waste materials as low-cost adsorbents for industrial wastewater treatment.

Summary: The study compared the activation of peroxymonosulfate (PMS) by zero-valent iron (Fe-0) and zero-valent aluminum (Al-0) for waste activated sludge (WAS) conditioning. Fe-0/PMS treatment showed superior dewaterability of WAS and reduced operational costs compared to Al-0/PMS treatment. The study proposes a novel perspective for selecting an optimal PMS activator in sludge treatment to alleviate environmental risks.

Summary: Magnetized activated carbons (MAC) prepared from rape straw powder showed high adsorption capacities for Pb(II) and Cd(II) due to surface active points, with adsorption behavior conforming to the Freundlich model and pseudo-second-order kinetic model. Thermodynamic parameters indicated spontaneous and endothermic reactions. Adjusting the pH of the solution could enhance adsorption capacity, but competitive adsorption occurred in the presence of high-valent ions. Adsorption mechanisms included electrostatic attraction, surface complexation, and co-precipitation. The MAC material showed potential for heavy metal ion removal from aqueous solutions.
