Default Make your own oxygen absorbers

FINALLY, I came across someone confirming what I suspected already.
O2 absorber is a simple chemical reaction. Rusting Iron absorbs oxygen as it rusts.

Quote:
> snip< http://www.offthegridnews.com/letters-to-the-editor/...If you choose to make your own absorbers:
It will take about 6 grams of iron filings and 6 grams of sea salt for a 5/6 gal bucket. Mix the two elements together and place in a small paper envelope. Put 2 to 4 drops of water on the envelope just before it is placed in the grain. There is enough moisture in the grain to keep this process going for a long time if the bucket isn’t perfectly sealed.

This process is perfectly safe. The salt rapidly converts the Iron (Fe) to Iron Oxide (FeO, or Fe2O3). The oxygen is all tied up with the iron, thus leaving a near oxygen-free environment so the grain won’t oxidize. It is almost the same as nitrogen-packed; 78% of the air is nitrogen and that is about the only thing left when the oxygen is gone...
> snip <
Not just the COST of o2 absorbers, but the HASSLE and limited shelf life of trying to use just a few at a time.
And what do you do when tshtf and no more mail-order survival suppliers?

Iron filings/ $7.00 USD - One pound http://secure.sciencecompany.com/Iro...1lb-P6370.aspx
One pound should be enough to do 75 5 gal. buckets

I remember in a magnet book I had as a young scientist, they showed how to MAKE iron filings/dust.
Put STEEL WOOL in a glass jar with some bleach. cover and let sit a day or 2. The steel wool will rust into dust.
To remove the oxygen that's combined with the iron, you heat it in a sturdy spoon, cast iron pan, etc. over a gas flame until it turns black.

------------------------------
If you add some powdered charcoal and sawdust to the iron & salt, you have the ingredients for those chemical pocket/hand warmers.

Citizens of Nazi Germany failed to answer that question correctly. Will the citizens of 21stCentury America do the same ?
Or will they regain control of their government before it is too late ?

Default ummm.... wait a minute..

Doing a little more searching on this diy o2 absorbers.

So far I've found mixed reports on this. Of course, O2 absorber manufacturers & sellers aren't going to promote diy and some could even provide dis-info

One "positive"
http://www.truthistreason.net/how-to...r-food-storage

One "not so sure"
http://thesurvivalpodcast.com/forum/...p?topic=2272.0

I'm not really convinced either of these were adequate to prove it one way or the other.
I believe I read somewhere that steel wool often has a very light OIL coating it to prevent rust in storage. But maybe not. I do know that when iron oxidizes, it DOES consume oxygen. And salt enhances the effect.


I'm going to test this myself tonight, a couple different ways.
Will report any findings.

I think the difference in your first post and the last one is iron filings are different animals from steel wool. There will be a larger surface area with the iron filings. Thus a quicker and more complete chemical reaction. Just my thoughts on the subject.

Yes.
One article mentioned the iron filings (very fine) are mixed with plastic "grains" in commercial o2absorbers to provide max surface area and space between the pellets for air-flow.

You would think with thousands of members we have here, one would work at a plant that makes these things and give us the skinny.

What?! And have all the Self-Sufficient-Survivalists putting up their dry food WITHOUT being dependent on Just-In-Time Survival shopping?

400 lbs grain for 10 people = 4000 pounds

38 lbs wheat per 5 gallon bucket = 106 buckets

Times 7* years = 742 buckets, 742 mylar bags, 742 O2 absorbers
