- Abstract
Background: The development of micro-organism resistance in humans and the environment has been linked to the inadequacy of conventional treatment methods in completely eliminating antibiotics. The purpose of this research is to look at the potential for eliminating Amoxicillin (AMO) from aqueous environments using Nickel (II) Oxide Nanoparticles (NiO nanoparticles). Materials and Methods: In order to determine how successful NiO nanoparticles are in eliminating AMO, the impact of many important adsorption process factors, such as the initial concentrations of AMO (10-50 mg/L), pH (3-10), adsorbent dose (0.1-1 g/L), mixing rate (50-300 rpm), contact time (10-100 min), and temperature (15-45°C) was examined. Results: The greatest AMO removal efficiency was 99.48% at pH=7, 0.8 g/L of adsorbent, and contact time of 60 min. The endothermic nature of the adsorption process was suggested by the positive value of Ho. The observed physical adsorption was consistent with the Ho evolved during adsorption, which was less than 40 KJ/mol. The negative value of Go demonstrated that AMO absorbed on the NiO nanoparticles was a spontaneous process. Conclusion: Accordingly, NiO nanoparticles could be employed as a successful adsorbent to eliminate AMO from pharmaceutical wastewater.
