Summary: This study successfully tested the adsorption performance of magnetic nanocomposites loaded with activated carbon for removing Pb(II) ions from aqueous solutions. The activated carbon was prepared from castor seed shells through co-precipitation and thermal activation. The results showed that the prepared nanocomposites were more effective in adsorbing Pb(II) ions compared to raw castor seed shells.

Summary: Water pollution caused by various contaminants is a serious problem. This study aimed to evaluate the adsorption of Reactive Blue 49 onto untreated Peanut Shell. The effects of operational factors on the adsorption efficiency were investigated, and it was found that the maximum adsorption capacity of Peanut Shell for Reactive Blue 49 was 30.30 mg/g. The adsorption process followed the pseudo-second-order kinetic model and exhibited spontaneous and exothermic physisorption.

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: 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: 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.
