Carboxymethyl Salix powder membrane (CMSM) was subsequently prepared through wet spinning technology. The swelling properties of CMSM were investigated. The results showed that the swelling degree reached the maximum at 45 min, pH 5, temperature of 65°C, and a NaCl concentration of 0.04 mol/L, reaching 7.95 g/g. Through model fitting, it was found that CMSM fits well with the Fickian diffusion model in the early stage, while the entire swelling process fits well with the Schott model. Characterisation results indicate that the structure of CMSM is loose, porous, and uneven on the surface. This structure facilitates the diffusion of water molecules and enhances the water absorption performance of CMSM. The structure of CMSM is similar to the disordered structure of glass or plastic, presenting an amorphous structure. Additionally, CMSM exhibits good thermal stability.

FTIR, UV-vis, WAXD, SEM, elemental analysis, ESI-MS, and XPS measurements were employed to disclose the coordination structure of DDM-Phen-Eu. Based on the study of the Huang-Rhys factors and the Judd-Ofelt parameters, the introduction of DDM would decrease the reorganization energy, stabilize the coordinate structure, and improve the fluorescence quantum yield of DDM-Phen-Eu up to 90.68%. Due to the hydrophobic property of DDM component, water has been excluded from the coordinate structure of DDM-Phen-Eu, which generated the fluorescence from both Phen and the Eu(III) ions of DDM-Phen-Eu in aqueous solution. The fluorescence intensities of DDM-Phen-Eu remained stable in acidic, neutral, and alkaline solutions, even with the addition of NaCl.

Overall, results show that OSPW from the Kearl oil sands mine has relatively low concentrations of metals and trace elements compared to other industrial OSPW. Of the inorganic constituents introduced into the wetland from OSPW, six analytes (As, Ba, Cu, Mo, Ni, and U) were found to depurate by wetland treatment, were distributed among wetland media (water, sediment, plants), and translocated into water sedge and cattail tissue. Depuration of these analytes from the OSPW occurred mainly through sorption to sediment, while Mo and Cu had higher uptake and storage within plant tissue compared to the other analytes. No significant differences in metal uptake were observed between cattails and water sedge; root concentrations were higher than leaf concentrations. Root and leaf concentration factors were similar across years indicating that mechanisms of plant uptake were not impacted by exposure to OSPW and that bioconcentration was mainly a function of exposure.
