Synthesis of graphene aerogel for adsorptive removal of tetracycline from water: Impact of operating parameters

Graphene aerogel (GA) was synthesized by chemical reduction of graphene oxide (GO) using ethylene diamine as a reducing agent, which was then followed by a freeze-drying process. In this work, we produced GA by hydrothermal process followed by freeze-drying. The produced adsorbent was then deployed to study the TC adsorption process.
