| Description |
The adsorption-influencing factors such as pH, dose, and time were optimized by batch adsorption study. A 0.8 g dose, 4.0 pH, and
80 min of contact time were optimized for maximum adsorption of Pb on AP. e adsorption isotherms (Langmuir and Freundlich)
were well fitted to the data obtained with values of max (16.39 mg/g; r2 = 0.985) and K (16.14 mg/g; r2 = 0.998), respectively. The
kinetics study showed that lead adsorption follows the pseudo-second-order kinetics with correlation coefficient (r2) of 0.999 for
all of the concentration range. FTIR spectra also showed that the major functional groups like polyphenols (–OH) and carbonyl
(–CO) were responsible for Pb binding on AP. The thermodynamic parameters as ΔG, ΔH (33.54 J/mol), and ΔS (1.08 J/mol/K)
were also studied and indicate that the reaction is feasible, endothermic, and spontaneous in nature.
