Resumen:
In this work a chitosan membrane (CH-0,5) was used for chiral separation byenantioselective sorption of Tyrosine (Tyr). The membrane was prepared from anacidic aqueous solution of 2% (p/p) of Chitosan containing 1% H3PO4 and theninsolubilized by adding NaOH (0.5M). The study of D-L-Tyrosine in chitosan membrane was carried out using a racemic mixture of Tyrosine (0.25-2 mM) at 25° C and pH 5.6.Tyr sorption isotherms were determined by HPLC. Results from FITR measurementsindicated that Tyr is present in chitosan matrix but no new covalent bond was formed.
