Effect of Temperature on Adsorption of Di-n-Butyl Phthalate Easter in Soil Minerals

Abstract:

The aim of this study was to investigate the effect of temperature on adsorption behavior of di-n-butyl phthalate (DBP) in kaoline and montmorillonite. Adsorption isotherms experiments were conducted at 288, 298 and 308 K, respectively. Results showed that adsorption capacity decreased and adsorption intensity enhanced with temperature increased in both minerals. Adsorption amount was larger in montmorillonite than in kaoline. Thermodynamic data indicated the process was a spontaneous and exothermal process and the dominant affection was physical adsorption.
