How To Make Deuterium??
« on: June 13, 2008, 06:33:49 AM »

 I know Deuterium is and isotope of hydrogen and it occurs naturally in 1/3200 parts of H20
Can you make Deuterium, Can deuterium ions bond with tritium and hydrogen particles.

P.s. ive asked this question as part of a project for advanced chemistry course.

Explain "make". What are starting materials.

One of every 6500 Hydrogens is deuterium, that is a hydrogen atom with 1 neutron, 1 proton. So deuterium is very rare, but you can most definetely "make it".

You don't actually make it because its already made, but you can separate the deuterium from the regular hydrogen, once process is by water electrolysis.

You get say 10 gallons of water, you make electrolysis until you have say 1 liter left, because deuterium is heavier (my speculation) you end up with all the heavy water in the 1 liter, you do it again, again you have all the heavy water, again, again, again, again, and at one point you will start to actually hydrolize the heavy water rather than the regular water, when you do this you will get pure deuterium.

Note that you will get very little deuterium from this water, you will need thousands of liters of water to make decent amounts of deuterium.

I'm sure there is other processes, but this is the one you can make at home, will take you a long time (and energy) to get a decent amount though.

This guy explains it very well.

It is my guess that the deuterium will act the same as the hydrogen gas and you will not get heavy water.

The centrifuge process might have some luck.

I think you will find that discussion somewhere in this forum.

There is some indication that an industrial process uses the electrolysis so Let me know if you actually get heavy water from this home process.

Very smart correlation Borek!

I once read a book called Attack on Telemark about the sabotage done by the Norwegian resistances forces and supported by the British. Supposedly the Nazis were very close to obtaining enough D2O to make a function pile.


Indeed, heavy water is isolated by electrolysis.

Learn something new everyday!

Thanks for teaching me that Argos; I can only assume that this process is much less energy/time intensive than the cascading electrolytic method.


D2O is still way too expensive though!

                             Copy of the lost replay No. 7

Dear Fleaker;

But remember that today heavy water is made by Girdler Sulfide (GS) process and fractionating distillation because the difference of Boiling points:   BP D2O  = 101.4°C   BP H2O = 99.97°C


Good Luck!

Heavy water (D2O) used to be made on an industrial scale in Ontario by the chemical exchange with and fractionation of H2S/D2S.  The heavy water is used as the neutron moderator in CANDU (CANadian Deuterium/Uranium) reactors.  I believe the plants are long gone so either they get it from somewhere else or they have all they need.

Isn't it possible just to radiate regular water to get D2O then just extract the deuterium ???

Possible, yes. Practical, no. Nuclear transmutation is slow and expensive (and hydrogen has a fairly small neutron capture cross-section).
Out of idle curiosity, does anyone know if the cooling water from nuclear plants is significantly enriched in D?

The little I do know is that CANDU reactors coolant need to be detritiated, but I believe tha major sources of tritium is from fuel and secondary neutron sources.
Light water reactors do not suffer from significant deuterium enrichment (as far as I know) for several reasons:
1. It would be really bad for reactivity control purposes.
2. PWR's continiously bleed coolant in order to dilute the chemical shim, the water usually end up in the plant discharge, after purification of course. (I don't know enough of BWR's but I am sure some water is bled off to sustain water quality).
3. Thermal neutron capture cross section for hydrogen is 0.3326 barns (not the lowest but in the top 15).
