چکیده:
Dyes are widely used in various fields, and their discharge into water. Causes environmental pollution effluents from many industries are rich incolour, acid and organic solvents. These effluents readily deteriorate the quality of receiving waters and soil, which eventually are harmful to human. The removal of colour from waste water by adsorption method has these advantages, that is, simply designed, easy to handle and inexpensive (Weber, 1972). In this study thermodynamic and kinetic parameters of surface adsorption of chryosoidin G on activated carbon granules in water solution at different tempretures were investigated. Adsorption equilibrium data were correlated with the Langmuire and Freundlich isotherms. Thermodynamic parameters such as S, H and G were calculated. The kinetic followed a pseudo firstorderreaction, and was fitted to the mass transfer model proposedby Lagergren .
