“…However, for both hydrogels, the χ 2 and RSS values (Table S6) of the pseudo-first and pseudo-second order models were found to be similar. Thus, the adsorption kinetics of Cu 2+ by both hydrogels could be adequately described by both models, indicating that the adsorption of Cu 2+ involved physical and chemical adsorption processes [41][42][43][44][45].…”

This research explores the integration of DUT-67 metal organic frameworks into polyethyleneimine-based hydrogels to assemble a composite system with enough mechanical strength, pore structure and chemical affinity to work as a sorbent for water remediation. By varying the solvent-to-modulator ratio in a water-based synthesis path, the particle size of DUT-67 was successfully modulated from 1 μm to 200 nm. Once DUT-67 particles were integrated into the polymeric hydrogel, the composite hydrogel exhibited enhanced mechanical properties after the incorporation of the MOF filler. XPS, NMR, TGA, FTIR, and FT Raman studies confirmed the presence and interaction of the DUT-67 particles with the polymeric chains within the hydrogel network. Adsorption studies of methyl orange, copper(II) ions, and penicillin V on the composite hydrogel revealed a rapid adsorption kinetics and monolayer adsorption according to the Langmuir’s model. The composite hydrogel demonstrated higher adsorption capacities, as compared to the pristine hydrogel, showcasing a synergistic effect, with maximum adsorption capacities of 473 ± 21 mg L−1, 86 ± 6 mg L−1, and 127 ± 4 mg L−1, for methyl orange, copper(II) ions, and penicillin V, respectively. This study highlights the potential of MOF-based composite hydrogels as efficient adsorbents for environmental pollutants and pharmaceuticals.

“…47 The higher COD removal efficiency of the MnO 2 /PMS system than the MnO 2 -EC system is possibly associated with the higher oxidation activity of SO 4 ˙ − generated from PMS activation than that of ˙OH. 48 Subsequently, the average current efficiency (ACE), instantaneous current efficiency (ICE) and electrochemical energy consumption (EEC) during the degradation process are calculated and compared for the three kinds of system (EC/PMS, MnO 2 -EC and MnO 2 -EC/PMS) on the basis of the above COD removal rate in Fig. 6a.…”
