Popis:	Almond shells are considered as agricultural waste. In this study almond shells were chosen as effective adsorbents for removing Crystal Violet (CV) from dye solutions. The experimental data was analyzed via the Langmuir, Freudlich and Tempkin isotherm models to obtain isotherm model for the system and the data shows that the Langmuir isotherm model fitted best. Also, the thermodynamics parameters such as Delta H-0, Delta G(0) and Delta S-0 were investigated. The results of the study show that almond shells are efficient and advantageous economically for removing CV from aqueous solutions. The maximum adsorption capacity was found to be 1.1375mg/g on almond shell. Adsorption kinetic studies indicate that the adsorption data can be represented by a pseudo second order model.
