wise words from Eugene. For best result, read posts from bottom up. A ---------- Forwarded message ---------- From: Eugene I. Gordon <[email protected]> Date: 2009/9/22 Subject: RE: OH To: Andrew Lockley <[email protected]>
Andrew: Sure, use the material. My background in this area is that I work on using O3 for sterilizing surgical instruments. I am not a chemist but the chemistry is pretty well known. http://www.fmi.fi/research_atmosphere/atmosphere_2.html I forgot to add that UV breaks up the oxygen molecule to form two O1 atoms, each of which combines with a O2 molecule to form O3. This is the classic explanation for how O3 is produced in the atmosphere. Right now the UV from the sun is way down because sunspots produce most of it. Ozone production is way down. And now may be a good time to do atmospheric chemistry since not too much is going on. There may still be enough UV to convert SO2 to H2S04. The point of all this is don’t ignore the chemistry. This is fairly straightforward but a lot can be going on. -gene *From:* Andrew Lockley [mailto:[email protected]] *Sent:* Tuesday, September 22, 2009 4:04 AM *To:* Eugene I.

Gordon <[email protected]> Do not ignore that the basic effect is that OH and O2H radicals are produced by ozone interacting strongly with H2 and even with H2O or other molecules containing hydrogen moieties. Both radicals are incredibly strong oxidizers and have a short lifetime, perhaps a minute or less if there are hydrocarbons around. *They do not destroy the ozone, the H2 and other molecules do*. The water may be a factor. If a volcano produces H2, it will harm the ozone layer. The radicals are not the cause but the result. [Incidentally the idea of a hydrogen economy, e.g., fueling vehicles with hydrogen fuel cells is total insanity. Leakage would destroy the ozone layer quickly just as did the old time refrigerants.] Here is what happens with a volcano: [image: Image:Volcanic injection.jpg] Notice where the acid rain comes from. Notice that UV converts SO2 to H2SO4. I am not sure what role OH plays but it seems to be unimportant in the process of interest. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "geoengineering" group.
