Summary: The synthesis of the organic ligand EBMS and its immobilization onto mesoporous silica led to the successful fabrication of a composite adsorbent (FCA) for the separation, adsorption, and recovery of Tm(III) ions. The FCA displayed high kinetic performance and was unaffected by competing metal ions. The adsorption behavior of Tm(III) ions on FCA followed the Langmuir adsorption isotherm model with a maximum adsorption capacity of 168.57 mg/g. The FCA showed strong selectivity and potential for the effective separation and recovery of Tm(III) ions from waste samples.

Summary: Organic ligand-based sustainable composite hybrid material (CMHs) was synthesized for the sensitive and selective adsorption of Lu(III) from waste samples. The adsorption of Lu(III) was influenced by solution pH, with slightly acidic conditions chosen for optimal separation and adsorption. Other metal ions did not interfere with Lu(III) adsorption due to the high affinity of Lu(III) to CMHs. The CMHs exhibited a high adsorption capacity and the adsorbed Lu(III) ions were easily eluted for regeneration.

Summary: With the increasing demand for precious metals such as palladium (Pd) and gold (Au) in modern industry, the discharge of Pd(II) and Au(III) wastewater has caused environmental pollution and resource shortage. In this study, a new metal-organic frameworks adsorbent (MOF-AFH) was synthesized to efficiently separate Pd(II) and Au(III) from water. The experimental results demonstrate that MOF-AFH has excellent selectivity and can be repeatedly used with a removal effect of over 90%.

Summary: In this study, fibrous chitosan/cellulose composite was prepared using the wet-spinning method to increase its specific surface area, thus enhancing the adsorption capacity towards Co(II). The as-prepared fibrous composite showed a homogeneous fiber structure and high specific surface area, leading to a significant improvement in Co(II) adsorption capacity. The adsorption kinetic behavior followed the pseudo second-order kinetic model, and the amino groups along with hydroxyl groups played a dominant role in Co(II) coordination and adsorptive removal.

Summary: Surface-enhanced Raman spectroscopy (SERS) is a powerful tool in biophysics, bioanalytical chemistry, and biomedicine for monitoring extracellular chemical activity. However, the limited choice of SERS nanotags has hindered its practical application. This study repurposes fluorescent chemosensors as SERS nanotags, using a plasmon-induced reaction to immobilize them onto plasmonic nanostructures. The results demonstrate the successful immobilization and functionality of xanthene-based chemosensors as SERS chemosensors.

The MicroPCMs demonstrated exceptional thermal storage and protective characteristics.
