:Adsorption is an important surface operation in unit operation and unit processes. Among many type of adsorbent material activated carbon are the most widely used, because of their large adsorptive capacity. Cost is an important parameter for comparing the adsorbent material. Among many such materials like turmeric waste, ferronia shell waste ,Jatropha curcus seed shell waste, delonix shell waste and ipomea carnia stem, Tea waste isone such alternatives which is cheap easily available. Activated carbons tea waste prepared by chemical activation with sulphuric acid as an activating agent .The effect of activation parameter such as carbonization temperature, sulphuric acid concentration ;contact time on the final products was studied by varying the H2SO4 to tea waste ratio, activation temperature and preheat –temperature.
