To date, it has been regarded as one of the most challenging issues to construct novel adsorbents possessing excellent adsorption performance toward heavy metals including copper ions (Cu(II)). Especially, it is controversy about the structural characteristics of chitosan-based adsorbents adsorbed with Cu(II) ions, which could function as new adsorbents. In this study, we adopt a freeze-drying process to synthesize honeycomb-like chitosan hydrogel beads crosslinked with citric acid (cCHBs), further characterize the microstructures of cCHBs and eventually reveal the thermodynamics equations for the removal of target Cu(II).

The increasing reliance on electronic devices has created a pressing demand for high-performance and sustainable electromagnetic interference shielding materials. While conventional materials, such as metals and carbon-based composites, offer excellent shielding capabilities, they are hindered by high costs, environmental concerns, and limitations in scalability. Polysaccharide-based materials, including cellulose, chitosan, and alginate, represent a promising alternative due to their biodegradability, renewability, and versatility.

Migration characteristics and occurrence forms of redox-sensitive metal(loid)s such as arsenic (As), chromium (Cr), and vanadium (V) remained unclear in dynamic estuarine waters. In this work, size fractionation and chemical speciation of As, Cr, and V in the Jiaomen Waterway (JMW), a tidal river of the Pearl River estuary, were explored based on (ultra)filtration, the diffusive gradients in thin films (DGT) techniques and a thermodynamic chemical equilibrium model. The results showed that As was present mainly in soluble forms in the river water, and the suspended particulate matter (SPM) was identified the major carrier for Cr.

The interaction between dissolved organic matter (DOM) and ferrihydrite (Fh) is a crucial process to control the environmental behavior of heavy metals (HMs) in soil environments, with DOM playing a particularly strong role in HMs fate. Since chemical properties of DOM vary based on different soil parent materials, the underlying impact of DOM-Fh associations on HMs binding remains unclear. This study systematically investigated the interactions between DOM from three soil parent materials (fluvial alluvium: FDOM, sand-shale: SDOM and granite: GDOM) and Fh, and meanwhile understand their effects on the environmental behavior of Cd and Pb under various environmental conditions.
