Authors: Daware, Gaurav B.; Gogate, Parag R.
Abstract: Adsorption of 3-Aminopyridine (3AP) from simulated effluent using sugarcane bagasse
activated carbon (SBAC) was studied based on batch and continuous operations. Characterization of synthesized SBAC was performed initially using BET and SEM analysis.
Different batch experiments were performed to understand the effect of operating
parameters such as initial concentration, pH, SBAC dose, time and temperature to
understand the effect on the extent of adsorption. The maximum adsorption capacity for
batch adsorption was established as 54.4 mg/g whereas the maximum extent of removal
was 97.6 % under optimized conditions. The observed data at equilibrium was found to
be best fitted to Freundlich and Langmuir adsorption isotherms. Kinetic study revealed
that pseudo-second order mechanism prevailed. Desorption of 3AP using ethanol showed
good reuse efficacy for five cycles. Column adsorption experiments were also performed
under varying SBAC bed height, concentration of 3AP and volumetric flow rate of 3AP
solution to determine the breakthrough parameters. The fitting of the Yoon–Nelson
and Thomas adsorption models to the obtained breakthrough data was studied and
found to be satisfactory. Maximum adsorption capacity of SBAC for adsorption of 3AP in
continuous operation was established as 65.6 mg/g. The obtained results demonstrated
very good performance of SBAC for effective removal of 3AP in both batch and column
operations.2020-05-23T00:00:00Z
