Photocatalytic Degradation of Co-amoxiclav Antibiotic Using Ag_۲O/GO/TiO_۲ Nanocomposite From Aqueous Solutions

Background: In this study, the removal of Co-amoxiclav antibiotic from aqueous solutions was investigated using Ag۲O/GO/TiO۲ nanocomposite during a photocatalytic process.Method: The effect of pH parameters (۱۱-۳), time (۱۲۰ min), initial concentration of antibiotics (۵-۵۰ mg/L) and dose of nanocomposite (۰.۰۴-۰.۰۱ g) in removing the studied antibiotic was investigated. During the experiments, a UV lamp was used to study the photocatalytic degradation, and the remaining concentration of co-amoxiclav and cephalexin antibiotics was determined by UV-VIS spectrophotometer.Results: The results demonstrated that the optimal parameters for the degradation of co-amoxiclav utilizing the nanocomposite are as follows: pH ۹, nanocomposite dosage of ۰.۰۲ g/L, a reaction time of ۶۰ min, resulting in a removal efficiency of ۶۶.۹۲%.Conclusion: This study showed a moderate efficiency of nanocomposite in removing antibiotics, which can be of interest in the research on development of nanotechnology in removing pharmaceutical compounds from water. However, more attention should be paid to the effects of their residual nanomaterials on the environment.
