Investigating morphology and performance of cellulose acetate butyrate electrospun nanofiber membranes for tomato industry wastewater treatment

Abstract

a b s t r ac tIn this research, cellulose acetate butyrate (CAB) electrospun nanofiber membrane (ENM) was prepared by electrospinning method in order to separate the contaminants of an industrial wastewater. The influence of various electrospinning parameters on morphology and average fiber diameter of the membranes were investigated by scanning electron microscopy and image analysis. The permeability of the membranes was evaluated by measuring pure water flux. In order to investigate the performance of the prepared membranes for tomato wastewater treatment, the rejection of the pollution indices and flux were determined. The results demonstrated the potential of using CAB nanofiber membrane for wastewater treatment. The appropriate electrospinning conditions led to preparation of the membranes with high water permeability in the range of microfiltration, proper retention efficiency in the range of ultrafiltration and noticeable antifouling property.

Nanofibers as novel platform for high‐functional ion exchangers

“…These unique features are vital for their applications as separation membranes and adsorbents. There are reports on the applications of nanofibrous mats for microfiltration and ultrafiltration processes which showed better performances, such as a high water flux and high removal efficiency, than the conventional ones.…”

Oleo‐Dispersions of Electrospun Cellulose Acetate Butyrate Nanostructures: Toward Renewable Semisolid Lubricants

“…Thus, the electrospinnability of CAb has been addressed in a few previous works. [27][28][29][30][31] Huang et al discussed the formation mechanism of a parallel line surface on electrospun CAb fibers using a solvent mixture of acetone and N,N-dimethylacetamide, which was attributed to the formation of voids on the jet surface at the early stage of electrospinning and subsequent elongation and solidification of the voids into a line surface structure. [31] Tanvir et al created porous CAb nanofibers using electrospinning in high humidity conditions to explore their potential as oil sorbents.…”

“…The membranes also become more porous with a larger average pore size as a higher amount of OCT-MMT particles is embedded (Figure b). The more porous structure renders a higher surface area and provides a more effective platform for adsorption. , The incorporation of metallic or ceramic nanoparticles in the electrospinning solutions increases the electrospinning dope viscosity. , Higher viscoelastic forces of more viscous spinning solution resist the axial stretching during whipping; hence, larger fiber diameters are formed. , As shown in eq , the larger fiber diameter leads to larger pore sizes and slightly bigger pore volumes. , Based on the studies in the literature and eq , the pore size of the ENMs depends on both fiber diameter and porosity. However, the fiber diameter is the more dominant factor compared to the porosity of the ENMs.…”

“…The porosity of the fibrous membranes was determined by the following equations: 46 , 47 where ε and ρ are the porosity and apparent density, respectively. ρ 0 is the mean density of the polymers and MMT, and φ is the mass fraction of the materials (Chitosan, PVA, and MMT).…”
