Fabrication of chitosan and poly (vinyl alcohol) blend membranes with different concentration of chitosan

Nowadays, the technology of membrane has become famous and widely used in the world. Many types of membrane have been invented including the chitosan (CS) membrane and also the poly (vinyl alcohol) (PVA) membrane. The objectives of this research are to fabricate the blend membrane using of chitosan...

Many types of membrane have been invented including the chitosan (CS) membrane and also the poly (vinyl alcohol) (PVA) membrane. The objectives of this research are to fabricate the blend membrane using of chitosan and PVA with different concentration of chitosan, to study the performances and the morphology changes of each membrane.

The adsorption performance of the flat sheet blend membrane was evaluated through the adsorption of BSA solution and lysozime.

In a nut shell, different concentration of CS enhanced the performances and the morphologies of the membrane. 2008-05 Undergraduates Project Papers NonPeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/648/1/Nurain_Mansor.pdf Nurain, Mansor (2008) Fabrication of chitosan and poly (vinyl alcohol) blend membranes with different concentration of chitosan.
