Title: Determination of optimum conditions of crystal violet dye adsorption on almond shells
Abstract: 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 ΔH0, ΔG0 and ΔS0 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.
