Abstract
In this study, the removal of Malachite Green (MG) dye from the aqueous solution by the adsorption method onto Sesame Shell (SK) was investigated. The effects of solution pH, the initial concentration of the dye, adsorbent amount and contact time on the adsorption process were determined. The adsorption kinetic was modeled using first order and second (pseudo) order kinetic models. Langmuir and Freundlich isotherms were applied in this study. All of the experiments were carried at the room temperature (25°C) and at solution volume of 30 mL. The optimum results had been noticed at the following parameters pH 8, initial concentration of 20 mg/L, the adsorbent amount of 0,3 g and contact time was 40 minutes. The adsorption of MG onto SK was found to be more suitable for the second (pseudo) order kinetic model with correlation factor of R2= 0, 9998. The result was fitted with Langmuir isotherm (R2=0, 9997). The adsorbent capacity was determined to be 1,58 mg/g, the removal efficiency of MG onto SK was 93,45%. In this study, the SK was used as an adsorbent for MG removal and based upon the obtained results it is found to be an effective choice. On the other hand, it was concluded that the calorific value of 4122 Cal/g determined for the contaminated adsorbent was an attractive waste for incineration plants for the disposal of the contaminated adsorbent.
