Waste salt-assisted pyrolysis of antibiotic fermentation residue for biochar production and hexavalent chromium removal mechanism.
The accumulation of antibiotic fermentation residue (AFR) and pharmaceutical waste salt (WS) poses a severe disposal challenge. Herein, we report a WS-assisted co-pyrolysis strategy is proposed to convert these hazardous waste streams into an active material for hexavalent chromium (Cr(VI)) reduction. During pretreatme...
