AI Thread Summary
A project is underway to develop a medical device capable of absorbing oxygen at a rate of 200-300 ml per minute without using explosive materials. Iron powder was initially considered, but concerns about the oxidation rate were raised. Suggestions for alternative materials included bulk getters like barium or titanium, which can be tuned for specific absorption rates by adjusting mass and temperature. The discussion highlighted the need for more information on bulk getters, including resources for purchasing and further reading. Relevant references and links to commercial suppliers of titanium powders and other getters were provided to assist in the research. Additionally, a pyrogallol solution was mentioned as a potential option.

I am working on a project of a medical equipment which is supposed to absorb oxygen at a rate similar to the human body. I am looking for a process or a substance that would absorb about 200-300 ml of oxygen per minute. I can't use fire or anything that explodes. I was thinking about iron powder, but I don't think the oxydation reaction would have the correct rate. Does anyone know if iron is OK? Any other suggestions?

Thanks,

Tiago

Have you looked into standar bulk getters like barium or titanium ? By fixing the mass of the getter and its temperature, you can tune the gettering rate.
 
Thanks a lot for the help. I really think bulk getters are what I need, though I'm not familiar with the term. I've googled "bulk getters", but I didn't find a lot of information that could help me. Do you know any websites or books with information about bulk getters or where to buy them?

Pyrogallol solution?
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
