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: Zirconium metal organic framework (Zr-MOF) was synthesized by hydrothermal method, and various spectroscopic methods were used for sample characterization. The adsorption of doxorubicin (DOX) onto Zr-MOF was studied. The effects of DOX concentration, contact time, solution pH, and temperature were investigated. The surface properties of Zr-MOF were determined by scanning electron microscopy (SEM). The adsorption efficiency of Zr-MOF for DOX was found to be higher at pH 6. The equilibrium isotherms and kinetic data were described using different adsorption models. The docking interactions between DOX and lung cancer and liver cancer receptors were evaluated.

Summary: This research focused on the removal of Fe(III) ions from wastewater using biosorbents made of natural palmyra palm fruit fibres (N-PPF) and chemically modified palmyra palm fruit fibres (C-PPF). The study found that the adsorption process was influenced by factors such as the dosage of the adsorbent, solution pH, and contact time. The Freundlich model provided the best fit for the adsorption data. The successful increase in functional groups during adsorption was confirmed by FT-IR and SEM-EDX analysis. The adsorption of Fe(III) was found to be an exothermic process occurring on the surface of heterogeneous adsorbents. The intra-particle diffusion model was suitable for explaining the rate-controlling step in the adsorption process of natural fibres.

Summary: In this research, a novel green tillite-based adsorbent (CMT) was synthesized by modifying the surface of natural/pristine tillite (PT) with Chrysophyllum albidum stem bark extract. CMT showed higher efficiency and adsorption capacity for Cr(VI) removal compared to most materials used for this purpose. The results also demonstrated the reusability of CMT and the chemisorption as the rate-controlling step. This study highlights the potential of Chrysophyllum albidum stem bark extract anchored on tillite as a green adsorbent for efficient Cr(VI) removal from polluted water.

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+.
