Article Citation - WoS: 10Ni-Zn Metal-Organic Framework Based Membranes for Rejection of Pb (II) Ions(Elsevier, 2022-12) Senol-Arslan, Dilek; Gul, Ayse; Uzal, Nigmet; Yavuz, EmreThe present paper describes a sustainable and affordable supply of clean, and safe water approach to investigate Ni-Zn MOF embedded membrane for rejection of Pb (II) ions in aqueous solution. Ni-Zn MOF powder was prepared by solvo-thermal method, and then the Ni-Zn MOF embedded membranes with various concentrations (0.025 wt%, 0.05 wt% and 0.1 wt%). The membranes were fabricated by a common phase inversion method. Phase solutions of Pb(II) prepared with PVP at different concentrations in aqueous solutions. Water filtration and Pb (II) rejection tests were operated on a batch scale. The prepared Ni-Zn MOF powder characterized by FTIR, SEM-EDX analyses and zeta potential measurements. Ni-Zn MOF membranes were characterized by FTIR, SEM-EDX analysis, contact angle, and water permeability measurements. The effects of important parameters on adsorption including concentration and pH were investigated. The obtained results indicated that the maximum rejection of Pb(II) was 98% for a feed solution containing 80 mg Pb/L at pH 8 and assistance with 2 % PVP for 0.05 wt% Ni-Zn MOF membrane. Additionally, it was detected that blend membranes revealed better Pb(II) rejection than pure PSF membrane.Article Citation - Scopus: 1Eco-Friendly Fabrication of Cellulose-Derived Polyvinylidene Fluoride Membranes From Wastepaper for Efficient Fe(II) Removal From Mine Wastewater(Wiley, 2025-08-15) Gul, Ayse; Senol-Arslan, DilekThis study investigates the feasibility of utilizing cellulose membranes derived from wastepaper to remove Fe(II) ions from mine wastewater. In this context, the recycled material cellulose was employed in the membrane synthesis process to produce an environmentally friendly membrane that efficiently removes Fe(II) ions. Furthermore, the study proposes a cost-effective and sustainable solution for removing heavy metals, with comprehensive analysis and experimentation on the potential application of cellulose membranes in the treatment of mine wastewater. The membranes were fabricated from polyvinylidene fluoride (C2H2F2)n (PVDF) and cellulose nanoparticles (CNs) produced from wastepaper by a common phase inversion method. Water filtration and Fe(II) rejection tests were operated on a batch scale. The fabricated CNs were characterized by Fourier transform infrared (FTIR) and SEM-energy-dispersive X-ray (EDX) analyses. Water permeability, contact angle, SEM-EDX analysis and FTIR were used to analyze PVDF/CN membranes. The water flux for PVDF and PVDF + CN membranes increased from 164.5 to 2241 L m-2 h-1 on the addition of CNs from 1% to 3%. The experimental results demonstrate the best cellulose membrane containing 11% PVDF + 2% CN effectively removed approximately 58% of Fe(II). The findings of this research emphasize the importance of environmentally friendly approaches in addressing clean water challenges and highlight the reuse potential of waste materials for innovative applications. Consequently, this study provides an alternative to the development of sustainable and cost-effective solutions for wastewater treatment in accordance with the principles of circular economy and environmental sustainability.
