Record #97593:

Diffusion and location of hydrochloric acid in ice: implications for polar stratospheric clouds and ozone depletion / Eric W. Wolff, Robert Mulvaney, K. Oates.

Title: Diffusion and location of hydrochloric acid in ice: implications for polar stratospheric clouds and ozone depletion / Eric W. Wolff, Robert Mulvaney, K. Oates.
Author(s): Wolff, Eric W.
Mulvaney, Robert.
Oates, K.
Date: 1989.
In: Geophysical Research Letters. (1989.), Vol. 16(6) (1989)
Abstract: Experiments involve freezing HCl solutions and observing them in scanning electron microscope fitted with X-ray microanalysis system. Shows that HCl is not easily incorporated into ice crystals, but is strongly partitioned towards grain boundaries. Diffusion of HCl through ice crystals is slow. Results contradict interpretation of earlier experiments, and mean that, if HCl is to be available for reaction on polar stratospheric cloud particles, as required by current theories of Antarctic ozone depletion, it must be present in some form other than solid solution.
