Chitosan/Cellulose Microfiltration Membranes for Endotoxin Removal

Abstract:

The aim of this study is the removal of endotoxin from water using a positively charged microfiltration membrane. The membrane was prepared by crosslinking a chitosan (CS) coating layer with glutaraldehyde vapor on a cellulose (CA) microporous substrate. The positively charged CS/CA membrane showed promising removal efficiency of endotoxin at a high water flux.
