The removal of color dyes from wastewater before they are released in natural waters is important
since some dyes are highly toxic for environment. Although several traditional chemical and
biological processes exist for dye removal, application of these techniques has been restricted
of low cost adsorbents suitable for dye removal. Since natural clays are ineffective as adsorbents
for organic compounds it is necessary to modify their surface. Chitosan-clay nanocomposites
are promising materials with organic-inorganic hybrid interfaces. These materials contain a
biopolymer chitosan and they represent a green alternative to conventional organoclays in their
applications, i.e. as adsorbents. The intercalation of chitosan into smectite clay can result in
monolayer and/or bilayer arrangements. When bilayer structures are formed some free –NH3
+
groups present in the interlamellar region are making these materials suitable for adsorption of
anionic species, i.e. anionic textile d...yes. In this work chitosan-clay nanocomposite was synthesized
using Na+-enriched smecite clay and characterized using physical-chemical methods. In
this manner the bionanocomposite with bilayered intercalation of chitosan chain was obtained
and tested as adsorbent. The adsorption of anionic dyes Acid Orange 10 (AO10), Acid Yellow
99 (AY99) and Reactive Black 5 (RB5) has been studied by varying the different adsorbate concentrations, temperature and shaking time. The concentration of commercial textile dyes was
analyzed before and after adsorption test using Thermo Electron Nicolet Evolution 500 UV-VIS
spectrophotometer in wavelength range from 250 – 800 nm.
