as the adsorbent. The adsorption characterization of activated chicken feathers by Na2S 0.1 N and non-activated chicken feathers was determined. Effect of variation experimental parameters pH, Contact time and variation dye concentration also being investigated in a batch adsorption method. Procion and Remazol Yelloow were characterized by UV-Vis spectroscopy
VV
The results show that the contact time and pH condition for adsorption equilibrium are 120 min for activated chicken feathers and 100 min for chicken feathers which were not activated by Na2S at pH 3. Procion red dye absorption by activated and not activated chicken feathers follows Freundlich isotherm and follow Langmuir isothrem. For remazol yellow dye absorption by activated and not activated chicken feathers follows Langmuir isotherm and Freundlich isothrem and the reaction kinetics follow the Ho equation.
