Oxygenation via H2O2 breakdown
    #4451136 - 07/25/05 05:17 PM (11 years, 4 months ago)

I was wondering if instead of fanning my casing, i would leave a reservoir of h2o2 next to the casing. the theory is that the gradual breakdown of h2o2 will be adequate gas exchange. one thing is, when h2o2 breaks down, it yields just O. the oxygen in the air that we breath is O2. what type of oxygen is needed for proper gas exchange? has anyone tried this before?

You could hook up an industrial oxygen bottle to an electric solenoid valve. Have the oxygen bottle cranked on at all times. A intervels during the day, the electric solenoid will be actuated by an on/off timer. When the timer comes on, your chamber gets filled with pure sterile o2. When the timer goes off your valve closes and the oxygen is cut off from your chamber.


:wink:

very true, i thought it could even evaporate with the water once. that was a dumb mistake resulting in a chemical burn.

Oxygen doubles up to o2 as it is made. You can get it to go to o3, but the British Commandos will blow up your factory. (Germans in WW2)

isn't pure oxygen bad. Aside from causing things to become extreamly flamable, It gets you sort of high, and i'm sure has some negative effects.

The problem isn't depletion of oxygen, but rather buildup of CO2. Various hydroxides (KOH, LiOH, NaOH, Ca(OH)2), ...) can be used to remove CO2 from the air. I have a paper where they used 1 M KOH for experimental mushroom cultivation, so that would probably be a good starting point for experimentation.

i know for a fact that atomic oxygen is bad for spacecraft because it can erode away the material by plucking off atoms with it's valence.

im sure it would contribute some oxygene, but would it be enough?

and also, as mentioned by pinback... the co2 buildup is more serious and will affect the growth before the lack of o2 does.

It wouldn't really break down fast enough. If you are misting with hydrogen peroxide and water, you should mix the two immediatly before you mist your terrarium. The H2O2 looses the 'extra' O atom fairly quickly in 'extreme' conditions, such as light and heat. You really need FRESH air and air currents to keep the casing layer clean and the CO2 levels down.
