•Sb(V) was rapidly reduced to Sb(III) in the anaerobic, calcareous soil.•Sb(III) was the dominant Sb species under reducing conditions.•The reduction of Sb(V) immobilized Sb, as Sb(III) binds more strongly to Fe phases.•The previously immobilized Sb(III) was released again under Fe-reducing conditio...
