Enhanced adsorption of perfluorooctane sulfonate and perfluorooctanoate by bamboo-derived granular activated carbon

- Granular bamboo-derived activated carbon is successfully prepared by KOH activation.
- The micron and nano-sized pores are suitable for PFOS/PFOA diffusion and sorption.
- The activated carbon has fast and high PFOS/PFOA adsorption.
- Spent activated carbon can be regenerated in 50% methanol solution.
