Abstract

Water pollution has consistently been an issue for the environment. TNT is commonly found in soil, groundwater, and surface water near manufacturing facilities due to inadequate disposal practices. The environmental permanence and human exposure to TNT degradation products are issues of concern. TNT endures because of inadequate biodegradation and photolysis rates. A multitude of scientists are exploring nanomaterials as a solution to this issue. Graphene oxide (GO) is one of the important carbon materials that can be used to remove traces of trinitrotoluene due to having several oxygen functional groups. Herein, the prepared Graphene oxide using the improved hammer method was applied to remove TNT residue from water. The as-synthesized GO was characterized by XRD, FTIR, and SEM. The as-prepared GO was applied as an adsorbent to remove TNT from water. Removal studies of trinitrotoluene were carried out using (HPLC). The effect of contact duration, pH, and temperature on adsorption has been examined. The findings revealed that the peak adsorption capability for GO was approximately 180.8 mg/g. We concluded that a pH of around 6 and a temperature of around 35 °C are optimal conditions for the elimination of TNT from water. The result indicated that the efficiency of removal exceeded 90.0%.
