Adsorption-based removal of amoxicillin from aqueous environments: A mini review

Abstract

Amoxicillin’s prevalence in aquatic environments, stemming from widespread medical usage, serves as a significant indicator of pharmaceutical contamination. Adsorption stands out as the preferred method for addressing this issue due to its simplicity, efficacy, practicality, and cost-effectiveness. This systematic review delves into peer-reviewed literature on amoxicillin removal through adsorption, drawing from databases like ScienceDirect and Scopus. Researchers have investigated adsorption equilibrium under varied conditions, exploring parameters such as pH, temperature, and adsorbent dosage. The diverse range of observed elimination levels underscores the critical importance of careful adsorbent selection, with capacities spanning from 10 to 1500 mg/g. Pseudo-second-order kinetic models and the Langmuir isotherm model frequently offer suitable descriptions of experimental data. Future research avenues could explore alternative kinetic models to deepen our understanding of amoxicillin adsorption mechanisms and foster the development of innovative adsorbents.
