The present research study investigates the potential use of the novel polyethylene terephthalate (PET) nanofibers extracted from waste bottles.The electrospinning process creates nanofibers which are then impregnated with dibenzo-18-crown-6 (DB18C6) (crown ether) to obtain a modified PET nanofiber.The use of modified PET nanofibers to remove methylene blue (MB) from aqueous solutions at different...
