Structural changes of regenerated cellulose membranes with gamma-ray irradiation

Abstract

The clearance of middle molecular substances and pure water permeability decreased significantly with gamma-ray irradiation for dry regenerated cellulose membranes. On the other hand, no changes in the clearance of middle molecular substances and pure water permeability were found for wet membranes. Many peaks were observed on the chromatogram of fluids eluted from dry and wet membranes. Gamma-ray irradiation reduced the strength of wet membranes.
