As of date, the comprehensive treatment for TNT red water remediation is not reported. In this study, TNT from red water was removed by using graphene nanocomposites (GNCs) prepared from graphite and sludge. The sludge used in the preparation of GNCs was obtained from the chemical coagulation of TNT red water using a mixture of organic acids as coagulant. The GNCs were intercalated with iron to produce few layered high surface area with high microporosity GNCs. The GNC prepared from sludge (GN-S) have shown high surface area and pore volume of 748 m2g-1 and 0.55 cm3 g, respectively. Owing to these textural properties, high adsorption capacity of 151.6 mg g-1 for TNT from TNT red water was achieved. The sludge generated during the treatment of TNT red water was used for GN-S preparation and this GN-S was proven as an efficient reusable adsorbent. The process of preparing GN-S from sludge and removing TNT from red water by adsorption onto GN-S aligns with the concept of circular economy.
