- •
The formations of SO4
− and OH, involve in Cr(VI) reduction induced by S(IV).- •
Affinity of polycarboxylate to Cr(VI) accelerates Cr(VI) reduction rate.
- •
Polycarboxylates can act as electron donors for Cr(VI) reduction retrenching S(IV).
- •
Only oxalate can enhance the formations of SO4
− and OH in Cr(VI)/S(IV) system.
