- Whist I think it's clear from previous postings that ozone replacement is
- not the solution, due mainly to it being a question of where the O3 <=> O2
- equilibrium lies. The position of this equilibrium has been (allegedly, for
- the sceptics) altered by the presence of CFC's . Is anyone aware of any work
- which has been done which may aid removal of the catalysts - in effect a
- chemical mop, which will 'soak up' the halogen radicals, and pull them out of
- the system. For example, one could notionally disperse sodium into the ozone
- layer, to form NaCl, which would be subsequently washed out without the
- possibility of forming further Cl radicals ( I am fully aware that this
- wouldn't work in practice, but it illustrates the principle).
-
- Just curious.
