Adsorption of orange G using activated carbon derived from common reed (Phragmites australis) in Mekong Delta, Vietnam
Activated carbon (AC) fabrication using agricultural waste biomass has been considered economical and sustainable. In this study, common reed (Phragmites australis)-derived activated carbon (CRPa-AC) was prepared via two consecutive stages, including pyrolysis and activation using K2CO3 and employed...
