The activated carbon (AC) was obtained from areca nut waste and it was further modified using succinic anhydrite under microwave reactor. The microwave-assisted process offers several advantages over the traditional methods in terms of selectivity in operation, fast and uniform irradiation, saving of time and energy and ease of control. The surface morphology of AC as well as modified AS were obtained by SEM image and the surface functional group present in the solid materials were discussed with FT-IR analysis. The synthesized material was further employed for the simultaneous removal of Hg(II) and phenol from aqueous solutions. Batch experiments showed that higher pH significantly favours the removal of Hg(II) whereas phenol removal was not affected by the change in pH of the solution. Moreover, various physic-chemical parameters such as effect of initial concentrations, contact time and background electrolytes concentrations were also investigated. |
