Abstract

Aim of this study, adsorption potential of modified and natural materials is investigated. The adsorbent used is watermelon peel (WP) derived from agricultural wastes to remove crystal violet (CV). The modified and raw adsorbent was characterized by Elemental analysis, Scanning electron microscope (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The studied parameters are temperature, initial metal concentration, and contact time. The most suitable kinetic (R2=0.99) and isotherm (R2=0.99) models were determined as Pseudo-second-order and Langmuir, respectively. The maximum adsorption capacity (qmax) according to Langmuir is 236.9 mg/g at 30°C. Thermodynamic analysis revealed spontaneous and endothermic adsorption of CV on modified watermelon peels. These results demonstrate that crystal violet can be removed from agricultural wastes using a low-cost adsorbent.
