ABSTRACT:
Vent gas containing disagreeable odor components consisting mainly of phenolic substances evolving from foundries using shell molding sand containing phenol resin as a binder is efficiently wet-treated by scrubbing the vent gas with an aqueous absorbent solution, to which a ferrous salt and hydrogen peroxide are added so that a ferrous ion concentration may be at least one-seventh of a hydrogen peroxide concentration, thereby making an oxidation-reduction potential of the aqueous absorbent solution have at least a value of (540 - 60 .times. PH value) mV, wherein the PH value is 5 or less.
