Aim of this research was synthesis of chitosan/bentonite nanocomposite
beads for colored wastewater treatment by adsorption. Influence of preparation
procedure on the morphology, adsorption and thermal properties has been studied. It
was proved that procedure method affects morphology, as well as enthalpy of absorbed
water evaporation, which depends on the molarity of NaOH, and does not affect glass
transition temperature. Chitosan adsorption capacity was improved by addition of
modified bentonite, which is desirable in colored wastewater treatment.Cilj ovog istraživanja je bila sinteza hitozan/bentonit nanokompozitnih
granula za prečišćavanje obojenih otpadnih voda metodom adsorpcije. Proučavan je
uticaj postupka pripreme na morfologiju, kao i na adsorpciona i toplotna svojstva
nanokompozitnih biopolimera. Dokazano je da način pripreme hibridnih granula utiče
na morfologiju, kao i na entalpiju isparavanja adsorbovane vode čija vrednost zavisi od
molarnosti NaOH, a ne utiče na temperaturu prelaska u staklasto stanje. Sposobnost
adsorpcije hitozana je poboljšana dodavanjem modifikovanog bentonita, koji je poželjan
u tretmanu obojenih otpadnih voda
