Abstract

In  this  research,  a  study  is  presented  on  the  synthesis  of  chitosan  derivative  Schiff  base  type  membranes  with benzaldehyde and crosslinking of chitosan with 2,4-pentanedione. Both chitosan and their derivatives were characterized by FTIR and UV-vis, a band were observed at 1620 cm-1 corresponding to changes in the absorption region of the C = N groups, also observed absorption of primary amine groups NH at 1654cm-1. Characterization by ultraviolet-visible spectra  observed  for  the  absorption  at  248nm  and  275nm  benzaldehyde  derivative  for  the  derivative  of  2,4-pentanedione.  The strength  and  filtering  capability  of  the  membranes  obtained  were  compared  by  concentrations  of  1.7%  m/v,  2%  m/v concentrations of 0.24% v/v of benzaldehyde and 0.23% v/v 2.4 -pentanedione, and found that membranes prepared by the reaction of chitosan with 2,4-pentanedione crosslinking showed the highest percentage of sodium removal, this was 92%.
