Biosorption Reactive Red 198 by using Chitosan

Adsorption processes are more effective methods for removal of toxic substance from aqueous solutions. In this study, chitosan was used as an adsorbent. In order to determine characterization of the chitosan; degree of deacetylation, molecular weight, apparent viscosity, fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction analyses were applied. Analysis results showed that chitosan has different functional groups. These different functional groups have reacted with reactive red 198. The adsorption of reactive red 198 at pH 5 was determined as 142. 85 mg/g at 200 mg/L initial dye concentrations. The effect of temperature on the adsorption shows that adsorption capacity increase with higher temperature. The pseudo second-order kinetic model was fit well over the range of contact times. Adsorption of reactive red 198 on to chitosan particle towards to chemical sorption.
