- •
Pennisetum alopecuroides as a new precursor first using one-step activation to produce activated carbons.
- •
Urea was employed to modify the activated carbons by phosphoric acid activation.
- •
The modified activated carbon was for improving its Ni(II) removal from aqueous solutions.
- •
The Ni(II) sorption mainly depended on the surface chemistry of the carbons.
