In The Name of Allah
The production of enantiomerically pure drugs is crucial to the current pharmaceutical industry due to the contrasting pharmacological effects
associated with the different enantiomeric forms of a drug.
So, we have prepare chiral
selective membrane from
chitosan substance from peel
shrimp)



2- What is chitosan:

Chitosan Preparation

A thin sheet of natural or synthetic material that is permeable to substances in solution.

Types of membranes

Ceramic Membranes

Liquid membranes
Biological membrane
polymeric Membranes

a) weight 3gm of chitosan in 10% aqueous solution of acetic acid pH=4

b) weight 5gm of polyvinyl alcohol (PVA) in 100ml of water.
c)Agition and heat (PVA) up to 60c
