“…It is notable that the incorporation of graphene oxide into PET bottle waste materials as a raw material for the production of membranes for wastewater treatment, as demonstrated in our work, allows the waste to be utilized for the fabrication of effective adsorbents for liquid phase contaminants. In turn, a ceramic membrane containing activated carbon derived from empty oil palm fruit bunches showed an iron ion removal efficiency of over 92% (C 0 = 1.38 mg/L, TMP = 2.0 bar) [ 30 ]. Polymer membranes based on polyethersulfone, into which PVP (polyvinylpyrrolidone, a pore-generating agent) was also introduced, exhibited a rejection efficiency of over 90% (C 0 = 5–20 mg/L, TMP = 3.0 bar) [ 31 ].…”

The present work reports an effective method for the removal of inorganic and organic pollutants using membranes based on different carbonaceous materials. The membranes were prepared based on cellulose acetate (18 wt. %), polyvinylpyrrolidone as a pore-generating agent (2 wt. %) and activated carbon (1 wt. %). Activated carbons were developed from residues after extraction of the mushroom Inonotus obliguus using microwave radiation. It has been demonstrated that the addition of activated carbon to the membranes resulted in alterations to their physical properties, including porosity, equilibrium water content and permeability. Furthermore, the chemical properties of the membranes were also affected, with changes observed in the content of the surface oxygen group. The addition of carbon material had a positive effect on the removal of copper ions from their aqueous solutions by the cellulose–carbon composites obtained. Moreover, the membranes proved to be more effective in the removal of copper ions than iron ones and phenol. The membranes were found to show higher effectiveness in copper removal from a solution of the initial concentration of 800 mg/L. The most efficient in copper ions removal was the membrane containing urea-enriched activated carbon.
