Abstract

In this study, we developing polysulfone-based composite membranes embedded with magnetic graphene oxide (MGO) for efficient mercury and oil removal. The results revealed that increasing the MGO nanoparticle concentration from 0 to 0.1 %Wt. led to a reduction in the contact angle from 68.2° to 56.7°, which enhanced the membrane hydrophilicity. The modified composite membranes with MGO nanoparticles showed greater surface roughness than the membrane without nanoparticles (M₀). It was also observed that the pure water flux decreased significantly with the addition of 0.1 %Wt MGO nanoparticles, from 239 L/m². h to 179 L/m².h. The highest mercury rejection efficiency was 94.35 % for the M₁ membrane at pH 6, whereas the M₁ membrane demonstrated a rejection efficiency of 96 % at a concentration of 250 mg/L during a 60-minute filtration. The composite membrane with 0.05 %Wt of MGO nanoparticles (M₁) achieved the highest oil rejection rate of approximately 96 % after 60 min of operation.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
