What would be the best substance to react with chlorine gas (in relatively small amounts, small enough where it probably isn't needed, but done just to be safe)?  I do not have a way to collect it into a pressurized tank, which I have seen people suggest doing, and it wouldn't be enough even if I did. 
I just need some substance to pass the gas through and react with it, so you know, it isn't super a super toxic gas floating around.

Alcaline Solution of sulphite or thiosulfate, will work
