Marshall,
I would very much appreciate a copy!
Thanks,
Steve

Subject: Re: CS>CS and killing of pathogens
I now have the full article. Anyone wanting it please let me know and
I will email it to you.
There are some problems with their methodology.
1. They say they make CS by two methods, one which leaves a residue of
silver nitrate in the solution, and the other which does not. I cannot
find which one they used for the data they are producing.
2. They say that they remove all AgO2 from the non-nitrate solution by
centrifuge. Fact is that it is impossible to removed dissolved silver
oxide and silver hydroxide by centrifuge.
3. Their curve shows a rise on the front end which indicates silver
oxide/hydroxide before adding HCl, but turns down after adding it,
indicating that ionic silver was converted to silver
4. They say that adding HCl produced silver chloride immediately as
evidenced by the solution turning milky, but that happens anyway with
silver oxide or nitrate in the solution from reactions with them.
5. They assume that the loss of the colloid is by producing silver
chloride instead of aggregation and precipitation when HCl is added. But
it is known that changing the pH of a solution significantly from 7 will
cause aggregation and precipitation.
5. Figure 5 shows a peak for colloidal silver of one size particle in
(b). In (c) it shows some AgCl peaks and a significant broadening of the
spectrum. This broadnening is I believe proof that instead of small
consistent particles, it now has variable sized particles, as would be
expected if the HCl was causing aggregation.
There are too many holes in the paper for me to be convinced that they
have not done junk science. I conclude from the data they have supplied
that the ionic portion reacted with HCl and that the colloidal portion
aggregated, which is exactly what I would have expected.
