Green approach for the synthesis of nanocomposite used as reactive material to containment amoxicillin and lead in groundwater

In this study, the environmental concepts were applied to preserve the environment by utilizing natural materials instead of harmful chemicals to synthesize a nanocomposite comprising quartz sand reinforced with Fe/Zn nanoparticles, wherein eucalyptus leaf extract was utilized as a green antioxidant, thereby eliminating the use of harmful chemicals. The nanocomposite was implemented as an active agent inside a permeable reactive barrier methodology to address the issue of stained groundwater with amoxicillin and lead. Based on the findings of this study, the nanocomposite can be considered a promising reactive agent in the PRB technology for the cleanup of contaminated groundwater.
