Scrubber material for aqua regia fumes.

[Perseus832]

Hi,
I’m just looking for some info on what kind of materials are best to neutralize AR fumes when gold refining.
I was thinking of using glass gas washing bottles and fill these up with maybe carbon or maybe limestone and connect it all with chemical resisting rubber tubing. I’m just not sure if this would work.
Any hints will be helpful
Thank you.

Not sure if the carbon or limestone would be efficient in scrubbing the gases fast enough. You can bubble the gases into a sodium bicarbonate solution which will be more effective

You need to build a scrubber like discussed here
