文摘

Activated carbon synthesized from golden shower through a new chemical activation method. A removal rate of 50%–73% achieved within 1 min in kinetic study. Maximum adsorption capacity at 30 °C (531 mg/g), 40 °C (614 mg/g), and 50 °C (678 mg/g). Primary adsorption mechanisms: π-π interaction and non-micropore filling. The π-π interaction identified by a new oxygenation method using acrylic acid.
