Decolourisation of Methylene Blue using Activated Carbon from Coffee Residue as a Low Cost Adsorbent
Activated carbon derived from coffee residues was utilized in this study. Batch adsorption experiments were carried out for the removal of methylene blue cationic dye from aqueous solution using different activated carbon samples. The activated carbon samples undergone two methods which are chemical...
