Summary: This study investigated the use of biochars derived from sugarcane bagasse as adsorbents for removing Mn(II) from aqueous solutions. The researchers found that pretreating the biomass with NaOH and using lower pyrolysis temperatures resulted in biochars with better adsorption performance. They identified the mechanisms of Mn(II) removal to be complexation between oxygenated groups and the metal, formation of MnO, and cation exchange. The biochar with the best adsorption performance achieved a removal efficiency of up to 65.8% for Mn(II) in real mining effluent. This research highlights the potential of using biochar for removing Mn in complex effluents and emphasizes the importance of studying these materials under real conditions.

Summary: This study reports a green and efficient method for the utilization of sugarcane bagasse waste through direct electroreforming, which produces green hydrogen and valuable chemicals using photovoltaic electricity. The electroreforming process avoids carbon capture and storage and has a low carbon footprint. Life cycle assessment shows that this method has the lowest global warming potential and holds promise for decarbonization and sustainable development.

Summary: In this study, sugarcane bagasse was treated to prepare adsorbents for removing Pb(2+) from wastewater, with nitric acid acting as an oxidant. The adsorption process was found to be exothermic and spontaneous, with the number of carboxylate groups on different adsorbents proportional to the equilibrium Pb(2+) adsorption amounts.

Summary: Adsorption is a promising remediation technology for separating organic and inorganic agrochemicals from contaminated soil and water. This study focuses on the use of iron-modified base-activated biochar (FeBBC) as a low-cost adsorbent for removing the insecticide imidacloprid from water. The FeBBC exhibits high adsorption capacity and both physical and chemical interactions contribute to the sorption process. The results demonstrate the potential of FeBBC as an effective adsorbent for removing organic contaminants.

Summary: This study investigated the adsorption properties of malachite green dye on two types of chitosan deep eutectic solvent adsorbents. The optimal pH and adsorption capacity under different factors were determined, while various characterization techniques were used to reveal the surface properties, crystallinity, pore sizes, and magnetic characteristics of the adsorbents. The results showed good fitting with the Langmuir model and the best description of kinetic behavior by the pseudo-second-order kinetic model for both adsorbents.

Summary: This study investigated the impact of different pretreatment strategies on sugarcane bagasse before citric acid modification in terms of Pb2+ adsorption capacity. It was found that pretreatment with ethanol and 0.01 M NaOH achieved high adsorption capacity, while pretreatment with 0.5 M NaOH and 0.1 M HCl led to lower adsorption capacity. Various analytical techniques were used to confirm the esterification between bagasse and citric acid, and the adsorption mechanism was well described by the pseudo-second-order model.
