How can I absorb amine fumes in storage?
Right now all my chemicals are packed in plastic boxes for storage with an open container of NaOH inside. This does a really great job of absorbing
moisture and acid fumes. Conc HCl and other chlorides are no problem.
What can I use for basic fumes? I have a bottle of triethylamine now and it already has a slight fishy aroma. My current idea is sodium bisulfate.
Conc sulfuric acid is too much of a hazard if it spills out.

That sounds reasonable. Although sodium bisulfate is hygrosopic and can turn to slush at high humidities (I've had it happen once), if you have sodium
hydroxide open and it's not a problem, you'll probably be fine with bisulfate.

Would a scrubber with citric or oxalic acid do the trick?

Cool so sodium bisulfate is hygroscopic.
I wonder if a mixture of CaCl2 and a weak acid like the mentioned citric or oxalic would be an effective dessicant. The acid won't be strong enough to
release HCl fumes.
Sodium bicarbonate is amphoteric and used in kitty litter products. A fridge air freshener might do the trick.

Sulfamic acid is a cheap, solid, non-hygroscopic, moderately strong acid (pKa = 1) that is probably perfect for your needs.

Boric acid is used to neutralize amines and amides.
