Abstract
The simple co-precipitation technique was followed to prepare an eco-friendly Chitosan/Polyvinylpyrrolidone magnetic composite in different ratios (CPF37, CPF55, CPF73) to exterminate Amoxicillin trihydrate (AMXT) from its aqueous environment. The batch method was practised to study the different parameters affecting the adsorption procedure. Among the three, CPF37 was found to be the best adsorbent for our study, owing to its highest adsorption capacity. The synthesized material was characterized using standard analytical techniques like FT-IR spectroscopy, XRD, SEM-EDX, TEM, VSM, TG-DTA, DSC, and Zeta-seizer. Furthermore, the efficiency of CPF37 reached up to 93% at pH 8 with 1 g/L optimized dosage for 100 mg/L AMXT solution at 308 K. The isotherm data attributed to multilayer adsorption, Freundlich isotherm (R2 = 0.9929) at 308 K and Qmax was calculated as 73.52 mg/g. The results from Kinetic studies concluded that the reaction followed pseudo-second order rate kinetic model, while the mechanism being the combination of several forces at a time. Moreover, Thermodynamic studies revealed the process to be endothermic (ΔH = +25.38 KJ/mol) and spontaneous (ΔG = −2.390 KJ/mol at 308 K).
