Can you do that with silica beads or just HCM? If not, what's special about HCM that allows them to be cleaned up?

I deal with carbon filters at work and we're usually looking at SO2 as the primary environmental contaminant. Let's assume for a minute that my humidor is sitting in a similar atmosphere, would either the silica or HCM adsorb the SO2? May not be applicable to a home humidor, but I'm curious
