文摘
- •
Thiol functional groups could be enriched via the redox reactions between sulfide and NOM.
- •
HA was found to be much more effective than FA in producing thiol functional groups.
- •
Higher thiols content resulted in both a faster U(VI) bioreduction and U(IV) reoxidation rate.
- •
Thiol groups are responsible for electron transport in U bioremediation and immobilization.
