Adsorption Of Lead (II) From Aqueous Solution By Activated Carbon Developed From Mangrove Wood By Microwave Radiation Heating

Activated carbon is an adsorbent that is large in surface area with a great amount of porous structure formed on it. Activated carbon is utilised as an adsorbent because of the effectiveness for adsorbing a wide type of contaminants in liquids or gases. This study aims to develop an activated carb...
