In past there was no significant comparative analysis between tea waste and egg shell for chromium removal were performed. And also activation of low cost adsorbent tea waste and egg shell by soxhlet was not done. Hence the objective of this work was comparitive adsorptive removal of hexavilanent chromium by acid activated and soxhlet activated tea waste and egg shell. Adsorption experiments were carried out for different parameters such as contact time, metal ion concentration and adsorbent dosages. In case of contact time other parameters such as metal ion concentration and adsorbent dosages were fixed. Similarly in adsorbent dosages and metal ion concentration other parameters were fixed and optimized from previous experiment.
