Batch experiments were used to evaluate the reductive immobilization of hexavalent uranium (U(VI)) by synthesized, amorphous iron sulfide (FeS) in the anoxic environment. The tests were initiated by spiking 168.0 μM U(VI) to 0.18 g/L FeS suspensions under a CO2-free condition with pH varied from 5.9...
