“…Adsorbents that can be reused have more advantages in practical applications because the reuse of materials can reduce the cost of adsorption. − The regeneration of adsorbents is an important step in reuse, and we used ethanol and acetone as eluents to regenerate Fe/Al-PCN-333–135(3:1) and Fe-PCN-333–150. The advantage of using organic solvent is that it facilitates the recovery of the CR dye through drying the solvent.…”

Bimetallic metal−organic frameworks (BMOFs) have garnered significant attention in the field of environmental remediation due to their more diverse adsorption sites compared to monometallic metal−organic frameworks (MOFs). Different energy barriers must be overcome for different metal ions and organic linkers to form MOFs. However, the impact of the synthesis temperature on the crystallization and porosity structure of BMOFs has been rarely studied. In this work, PCN-333 series-based BMOFs with different Fe/Al ratios were prepared by a solvothermal method at temperatures of both 135 and 150 °C. The synthesis temperature and Fe/Al ratio have significant effects on the crystal structure and specific surface area of bimetallic PCN-333, leading to the different adsorption performance of the PCN-333 for Congo red (CR). The Fe/Al-PCN-333−135(3:1) and Fe-PCN-333− 150 exhibited the maximum CR adsorption capacities of 3233 and 3933 mg/g, respectively, surpassing the capacities of most previously documented adsorbents. The Langmuir model and pseudo-second-order kinetics can well describe the adsorption process of CR on Fe/Al-PCN-333−135(3:1) and Fe-PCN-333−150. Combining the isotherm adsorption behavior with the thermodynamic parameters, CR adsorption on BMOFs is a single-layer endothermic chemical adsorption. Furthermore, Fe/Al-PCN-333−135(3:1) and Fe-PCN-333−150 exhibited regenerability and reusability for three cycles with reasonable efficiency. This work is of great significance in the field of engineering BMOF materials to treat dye wastewater.

“…The lower adsorption efficiency might be attributed to the leaching of La (29.3 mg L −1 after the first cycle), which reduced the active sites on SA-0.4La@De. 55 In addition, the strong chemical bonding between the adsorbed phosphate and adsorbent would also lead to irreversible adsorption of some active sites. 56 Thus, it is essential to enhance the stability of SA-0.4La@De for phosphate adsorption in the future.…”
