Abstract

Kinetic, Isothermal and Thermodynamic Studies from Adsorption of Textile Dye Ruby 2G Dianix onto Chitosan. Kinetic, isothermal and thermodynamic equilibrium experiments from adsorption of textile dye ruby 2G Dianix onto chitosan in aqueous medium were studied, as well as biopolymer characterization. Bath adsorptions experiments were realized and the pH results indicated the best range adsorption is between 4,0 and 6,0. The kinetic reaction suggests a second order rate law and the isotherm results agree with the Langmuir model. The thermodynamic parameters (ΔGº, ΔHº and ΔSº) also are presented in this work.
