Summary: Due to industrial activity, heavy metal contamination is present in water, air, and soil around the world, leading to serious environmental issues. In this investigation, natural kaolin (NK) clay was used as an effective adsorbent to remove Pb2+ from solution. The adsorption capacity and efficiency of NK were influenced by factors such as contact duration, dosage, temperature, and pH. It was found that NK had a maximum desorption efficiency of 93.07% and showed potential as an eco-friendly adsorbent for heavy metal removal.

Summary: The study investigated the use of Aluminium oxide modified onion skin waste for the adsorption of metal ions (Pb2+ and Cd2+) and analyzed the relationships between sorbent properties and metal ion sorption. Optimum values for initial concentration, contact time, adsorbent dosage, and pH were found to be 10 mg/L, 120 min, 1.6 g/L, and 6.0 respectively, resulting in maximum removal percentages of 91.23% for Pb2+ and 94.10% for Cd2+. Isotherm and kinetic studies suggested a multilayer adsorbate-adsorbent system with chemisorption mechanism dominance, and concluded that onion skin waste is a viable, cheap, and effective alternative for removing heavy metal ions from water/wastewater.

Summary: The aim of this study was to develop a new magnetic nanocomposite for removing Cu (II) from groundwater using walnut shell ash (WSA)/starch/Fe3O4. The nanocomposite was successfully synthesized and showed a high specific active surface area. The Cu adsorption followed the Freundlich and Langmuir models, and the process was spontaneous and exothermic. Kinetic adsorption data fitted the pseudo-second order model.

Summary: Hydroxyapatite (HAP) has excellent adsorption ability for Fe(III) and can effectively hinder the migration of Fe(III) under certain conditions. The transformation efficiency of Fe(III) is significantly influenced by the initial pH value and reaction temperature, and the adsorption kinetics of Fe(III) on HAP follows a pseudo second order kinetic model.

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: The study developed eco-friendly polymeric spheres derived from crosslinking of chitosan (CTS) with different polyesters. The spheres showed enhanced structure and stability in aqueous media, with decreased hydrophilicity, and were effective in adsorbing lead ions (Pb2+) from aqueous solutions. The experimental data was fitted well with the Freundlich isotherm model, showing the best fit for the adsorption process.

Summary: Heavy metal pollution is a significant public health hazard during industrialization, with various toxicological manifestations. Conventional remediation methods for heavy metal pollution control are limited due to cost and toxic by-products. In this study, autoclaved Saccharomyces cerevisiae was used as a biosorbent for the removal of Cd2+ and Pb2+ from aqueous solutions. The results showed that S. cerevisiae had stronger competitive adsorption ability for Pb2+ compared to Cd2+. The adsorption of metal ions on S. cerevisiae followed a pseudo-second-order kinetic model and Langmuir isotherms model. Autoclaved S. cerevisiae is a rapid and favorable biosorbent for Pb2+ and Cd2+.
