Activated Carbon Derived From Pentace Triptera, Intsia Bijuga And Hevea Brasiliensis Sawdust Via Microwave-Induced Potassium Hydroxide Activation For Dyes Adsorption

Synthetic dyes are widely applied in various industries which has resulted in the water pollution. Therefore, this study aims to synthesis activated carbon (AC) from Pentace triptera (PS), Intsia bijuga (IS) and Hevea brasiliensis (HS) for methylene blue (MB) and remazol brilliant violet 5R (RBV) dy...
