“…If a polymer solution with a higher concentration is used, then fibers of larger diameter are produced as compared to a diluted solution [ 50 ]. Zeitoun et al [ 51 ] investigated two different concentrations of polyvinylidene fluoride (PVDF)—14wt% and 16wt%—and observed that 16wt% solution of PVDF generated few beads with membrane structure. The reason for the generation of beads with membrane structure is that polymer induces long-chain entanglements, which are responsible for the continuity of the jet during the electrospinning [ 52 ].…”

This review covers recent developments and progress in polymer and biopolymer blending and material preparation by electrospinning. Electrospinning is a technique that is used to produce nanofibers to improve the quality of membranes. Electrospun nanofibers are highly applicable in biomedical sciences, supercapacitors, and in water treatment following metal ion adsorption. The key affecting factors of electrospinning have been checked in the literature to obtain optimal conditions of the electrospinning process. Future research directions and outlooks have been suggested to think about innovative ideas for research in this field.

Textile wastewater effluents yield tons of dyes that, even at low concentrations, are toxic and need to be removed before this water is disposed of in aquatic life. Methylene blue has a low degradation rate and causes severe harm to the environment even at low concentrations. Adsorption is an effective method of getting rid of these dyes. In this study sugarcane bagasse pulp, which is a waste resulting from the sugar extraction process, is examined as an adsorbent for the removal of methylene blue from textile wastewater. Batch experiments are carried out to determine the efficiency of the adsorption of methylene blue onto the sugarcane bagasse pulp surface. Seven different parameters including the adsorbent dose, temperature, initial dye concentration, contact time, pH, and adsorbent particle size are studied to determine their effect on the adsorption process; characterization of the adsorbent is carried out. Artificial neural network is used to determine the optimum conditions that give maximum efficiency. The results of this study showed that bagasse pulp is an effective adsorbent material for methylene blue removal with a maximum adsorption efficiency of 95%. Graphical abstract
