Activated carbons prepared by physical activation from different pretreatments of amazon piassava fibers

This study aimed to evaluate the effect of different pretreatments of Amazon piassava (Leopoldinia piassaba) fibers on microstructure, thermal, and physical properties of the ensuing activated carbons (ACs). ACs were prepared from untreated and pretreated piassava fibers by physical activation using CO2 at 800°C. Pretreatments include: mercerization, corona discharge, and removal of extractives. Scanning electron micrographs showed the formation...
