الخلاصة

Pomegranate peel was tested for its ability to adsorb amaranth dye from solutions with alterations in the parameters such as pH, contact time, sorbent weight, and temperature. The adsorption process was analyzed on the basis of pseudo-first-order, pseudo-second-order kinetic models and also by Freundlich and Langmuir isotherm models. The maximum adsorption capacity for pomegranate peel as calculated by Langmuir model was found to be 3.448mg/g and 3.560 g\ L at 25°C. Thermodynamic parameters such as the changes of free energy, enthalpy, and entropy were also evaluated. The results indicated that the sorption amaranth dye onto the pomegranate peel was an endothermic process that could be well fitted with the Langmuir adsorption model and pseudo-second-order kinetic model.
