Summary: Two novel absorbents were synthesized from banana and pomegranate peels for the removal of Cd(II) and Ni(II) in sewage systems through DTPA modification. The DTPA-modified peels exhibited higher adsorption capacities and faster adsorption rates, potentially attributed to ion exchange, complexation, and physical adsorption mechanisms. This study demonstrates the feasibility and effectiveness of utilizing waste peels as cost-efficient bio-absorbents for heavy metal removal.

Summary: Monochloroacetic acid precursor-based carboxymethyl chitosan resins were prepared and investigated for their adsorption properties of Zn, Pb, and Fe. The complexity of the adsorbate system and the co-existing cations significantly influenced the sorption characteristics of the multi-heavy metal ions. The carboxymethyl chitosan resin exhibited optimal adsorption capacities of 238.10 mg g-1 for Zn, 4.78 mg g-1 for Pb, and 147.06 mg g-1 for Fe. The resin could be effectively regenerated using low-cost acid-base solutions even after three adsorption-desorption cycles.

Summary: A physically crosslinked polyvinyl alcohol/phosphorylated chitosan (PPP) hydrogel electrode was designed using the freezing thawing method to improve the removal rate of uranium and reduce radioactive pollution. The PPP hydrogel showed excellent adsorption efficiency for uranium, with a treatment efficiency of 100% within 15 minutes for the absorption of 200 mL uranium tailings leachate. The PPP hydrogel exhibited good adaptability to a wide range of pH conditions and maintained an adsorption efficiency above 85% for a 950 mg/L uranium solution. The synergistic effect of various functional groups in the material, such as phosphate, hydroxyl, and ammonium, contributed to the adsorption capacity of PPP for uranium. Additionally, the electrochemical adsorption method significantly enhanced the adsorption performance of PPP hydrogel.

Summary: The novel depressant DTPA was found to effectively inhibit the floatability of fluorite while minimally affecting scheelite due to its selective adsorption on fluorite surface and hindering the further adsorption of NaOL. The chemical adsorption of DTPA on the fluorite surface allows for the potential effective separation of scheelite from fluorite.

Summary: This study investigated the retention of uranyl ions using a novel, natural and cost-effective adsorbent, humic acid (HA) embedded chitosan/polyvinyl alcohol (Ch/PVA-HA) bio composite. The Ch/PVA-HA achieved the highest adsorption capacity reported in literature in a column system. The batch tests showed that the adsorption isotherm of uranyl ions changed from Freundlich to Langmuir when the surface of Ch/PVA copolymer was covered with HA. The presence of HA enhanced the distribution ratio of uranyl ions between the adsorbent phase and aqueous solution.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
