        abstract = {Out of all forms of nitrogen, ammoniacal nitrogen is the primary contaminant of concern. The objective of the present study was to assess the viability of Activated Waste Tea (AWT) and Activated Groundnut-Shell (AGS) utilization for the removal of ammoniacal nitrogen from waste water. The batch experiments for both AWT and AGS were conducted and effects of various parameters (pH, adsorbent dosage, time, temperature and agitation time) were observed. The results indicated that at the optimum parameters for both AWT and AGS, the removal efficiency reached the maximum 98% and 97.54% respectively. Changes in surface morphology for the removal of ammoniacal nitrogen from the waste-water. and functional group modification before and after adsorption were examined by Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FT-IR) Spectroscopy. Additionally, kinetic measurements and isotherm studies have also been performed to understand the ability of the adsorbents. The results revealed that adsorption on AWT followed second order rate kinetics but on AGS followed first order rate kinetics. Furthermore, adsorption fitted well (in both) to Freundlich adsorption isotherm as compared to Langmuir model. The large adsorption capacity and the rapid adsorption rate indicated that AWT and AGS have great potential to be used as a cost-effective adsorbent.},
