This project presents a sustainable water filtration solution using electrospun cellulose acetate nanofiber membranes to remove microplastics and co-contaminants. By optimizing electrospinning parameters, the produced membranes demonstrated enhanced filtration efficiency and selective retention of various plastic types. Compared to conventional methods, the nanofiber structure improved mechanical strength, surface area, and microplastic adhesion. This eco-friendly technology shows great potential for environmental remediation and can be further developed for broader applications in water treatment.
