Özet
In this article, toxic Trypan Blue dyestuff was uptaken from water by adsorption method. Chitosan and synthesized chitosan phthalate were used as adsorbents. Adsorption processes were consisted of kinetic and thermodynamic studies. First kinetical experiments were made and the results were practiced to Lagergren, Weber- Morris and Ho- Mckay equations. Adsorption rate constants (kads) and pore diffusion rate constants (kp) were calculated. Then, thermodynamic experiments were performed at different temperatures. Some thermodynamic parameters (ΔH, ΔG and ΔS) and adsorption isotherms were determined. Because Langmuir adsorption isotherms were more suitable, Langmuir constants were calculated. These experiments were performed with both chitosan and chitosan phthalate and the results were evaluated.
