عنوان انگلیسی Thermodynamic, Kinetic, Batch Adsorption and Isotherm Models for the Adsorption of Nickel from an Artificial Solution Using Chloroxylon Swietenia Activated Carbon
چکیده انگلیسی مقاله ABSTRACT
Chloroxylon Swietenia tree bark was being used as an eco-friendly bio-adsorbent in our research work. This research work has investigated the adsorption efficiency of nickel by using a batch adsorption technique. Chloroxylon swietenia is commonly known as East Indian satinwood, which is popularly known as Porasu in Tamil. Chloroxylon swietenia activated carbon (CSAC) has been prepared from Chloroxylon swietenia tree bark as an adsorbent. Effective experimental parameters like carbon dosage, effect of pH parameter, contact time, pseudo-first order kinetic model, and Elovich model have been employed for the removal of nickel from an aqueous solution. The equilibrium data was calculated using adsorption isotherm models such as Langmuir and Freundlich. The percentage removal of nickel was calculated by thermodynamic parameters. The research studies proved that the removal of nickel by CSAC was endothermic as well as spontaneous in nature. The adsorption of nickel on CSAC has been determined by using the Fourier transform infrared spectroscopy technique.
