Adsorption of Methylene blue onto hydrophobic activated carbon
Activated carbon (AC) was prepared from date palm leaflets using NaOH activation. AC was oxidized using concentrated HNO3 to produce oxidized activated carbon (ON). Alkylamines including methylamine (M), dimethylamine (DM), ethylamine (E), diethylamine (DE), and diisopropylamine (DIP) were covalently immobilized onto O …
