Sincere apologies for stretching this out Marshall but just as an example:

 

One result...Total Ag (acidified HNO3)=23.5mg/l (clear solution)

 

12.0mg/l was soluble (filtered thru 0.45 micron paper), now ignore the filter 
part cos that doesn't mean a great deal to me, in fact it means nothing to me 
due to agglomeration of silver during filtering process, so I'd like to work on 
the soluble part.

 

AAS was incorporated somewhere in this sample testing also.

 

That 12.0mg/l soluble part would obviously contain ions and particles, and 
some, probly most...? would be well within the smallest size which is deemed a 
*must have size*, however, the larger ones, the ones that STILL passed thru 
that filter, would have to still be bio-available.  I am not so much concerned 
with that larger particle component as the other silver content will still be 
in abundance and still be somewhat efficacious.  Literature I have read states 
"for a substance to be classified as a 'colloid' that substance should be no 
larger than 1000nm or 1 micron in size".  Now couple that with the fact that I 
believe ALL the silver content falls WELL below that limit, and my visual 
observation of NIL settlement, you can see where I get my idea from, flawed as 
that may be praps, so if you can expand on all I have noted here it could be of 
some assistance to me.

 

If a suitable explanation requires considerable chemistry details and equations 
then don't worry about it cos it would go straight over my head, I'm just 
basically wanting to know if it's possible for you to give me a SIMPLE reason 
for why my clear solution came back with such a close balance of ions to 
particles, and why that result seems to be at odds with some.  Praps it's been 
said before at some time but if it's in chemistry language it probly went in 
one ear and straight out the other.

 

I'll let you decide if a reply is worthy of the time and/or effort.

 

N.
