Title: | Evaluation of the permeability of modified cellulose acetate propionate membranes for use in biosensors based on hydrogen peroxide detection | Authors: | Guiomar, A. Jorge Evans, Stephen D. Guthrie, James |
Issue Date: | 2001 | Citation: | Cellulose. 8:4 (2001) 297-301 | Abstract: | Phase inversion cellulose acetate propionate membranes showed lowpermeability to hydrogen peroxide aqueous solutions. Their permeability wasincreased by alkaline hydrolysis of the ester linking units. However, thepermeability remained lower than that of an unsubstituted cellulose membrane.The inclusion of hydroxypropyl cellulose in the membrane formulation, followedby an alkaline hydrolysis step, increased permeability to hydrogen peroxideaqueous solutions to 29% of that of an unsubstituted cellulose membrane. | URI: | https://hdl.handle.net/10316/7850 | DOI: | 10.1023/A:1015137809504 | Rights: | openAccess |
