| Abstract Scope |
Two-dimensional (2-D) nanomaterials have found their applications in water-treatment , due to their exceptional specific surface area, and superior biological, mechanical, and physio-chemical properties. However, the reagents used for their synthesis are noxious to human health and hazardous to environment. This study reports on two greener approaches based on “Encapsulation” and “Hydrothermal Treatment”, to the synthesis of graphene and 2-D-nano-sized MoS2 , respectively. Both of the materials synthesised were tested against organic dyes and other emerging contaminants and showed 96% rhodamine-b dye removal and 85% Ciprofloxacin removal. Detailed batch tests were done to examine the effects of adsorption time, adsorbent dosages, solution Ph and temperature. Adsorption mechanism was also investigated via thermodynamic calculations, adsorption kinetics, and isotherm modelling. The results indicated that the two 2-D nanomaterials prepared using the greener methods reported here could be potentially used as promising adsorbents for removal of organic pollutants from waste-water. |
