Ruthenium recovery from acetic acid waste water through sorption with bacterial biosorbent fibers

- A fibrous type of bacterial biosorbent was evaluated on its Ru sorption capacity.
- The maximum Ru uptake of PBBF was 16.5 times higher than that of commercial resin.
- The PBBF showed a highly effective removal of Ru in a column system.
- The PBBF has potential as a biosorbent for Ru removal from acetic acid wastewaters.
