Preparation and activation of activated carbon from waste materials-A review

Abstract

This paper gives information about different value added waste for preparation of activated carbon is used as adsorbent. There are different types of waste which can be converted into activated carbon by chemical activation using different activating agents like Cacl 2 , H 2 So 4 , H3Po4, KoH, and Zncl 2 .These activating agents are used by different investigators for activation of carbon prepared from waste at different performing conditions. Adsorption isotherms were developed by different authors with respect to their work.
