Development of Chitosan/PVA Nanofibrous Membranes for Efficient Removal of Microcystis aeruginosa

open access: yesJournal of Applied Polymer Science, EarlyView.
Removal of Microcystis aeruginosa from CS/PVA fibers by A‐HSBS. ABSTRACT In this study, chitosan/poly(vinyl alcohol) (CS/PVA) polymeric nanofibers were produced using the Air‐Heated Solution Blow Spinning (A‐HSBS) method and applied for the efficient removal of Microcystis aeruginosa from contaminated water.
