Colloidal silver and hydrogen peroxide
« on: September 13, 2020, 02:13:49 AM »
Today I made a 2 liter batch of colloidal silver and when I poured into my storage containers I had about 1 pint that didn't fit into the prepared jars.  I ended up pouring it into a jar that I had rinsed with hydrogen peroxide.  Since I was not going to keep it I just poured it into that jar.  It was a 10ppm silver and was gelatin capped and had a nice color.  About an hour later when I was cleaning up I noticed the Colloidal Silver I poured into the spare bottle was clear.  No sign of the original color when I poured it in.  The other Colloidal Silver from the batch looked great. 

I don't think there was much hydrogen peroxide in the other container but it had not been rinsed since it had hydrogen peroxide in it.  I usually rinse my used continers in hydrogen peroxide and follow with distilled water rinse.  Could this cause a problem?  What happened to the color? What did I have at that point?

Thanks again for all the help I have received from this site.

Hydrogen Peroxide destroys Colloidal Silver. Don't use it anywhere near Colloidal Silver.

Well, hydrogen peroxide does have its use.  You do build up a little silver deposit on the inside of your container over time and that works like a third electrode and screws things up.

To fix this, wash the jar out with soap and water and rinse a couple times (tap water is fine). Then dump in maybe an ounce of hydrogen peroxide (just so its said, by itself - no added water), cap, shake for a couple minutes and dump out.  It will remove ALL the silver deposits.

Now, rinse with tap water again 2-3 times to make sure you get all the hydrogen peroxide out, then rinse twice with a little distilled (add an ounce or two, cap and shake and dump) to get all the tap water out.  You'll be fine.

I do this once every maybe 10 batches as a matter of course.

As far as getting hydrogen peroxide (ANY amount) in contact with colloidal silver, yeah, what cfnisbet said (wink).  Even at 3% its a powerful oxidizer you don't want near Colloidal Silver.

How if the H2O2 mix with silver ion / ionic silver without reducing agent or capping agent?
because a lot of company said they use 3% hydrogen peroxide at 1.5% of 1 liter DW, AGNP and ethanol as disinfectant
Maybe they are using chemically produce AGNP?
Thanks

Hydrogen peroxide destroys silver nanoparticles, converts it back to ionic silver.  Use it to clean your glassware.  Peroxide also sank a Russian submarine,  but thats another story.
There is the unknown and the unknowable.  It's a wise man who knows the difference.

What happen if unreduced ionic silver ( without reducing agent or capping agent produce at very low amperage ) mix with hydrogen peroxyde, will it cancel out  its ability as disinfectant or sterilizer ?

No, it will remain ionic and effective as such, but only for cleaning your kitchen worktops etc.

We only use it for cleaning silver residue from glassware.

Yup, im planning to use it in disinfectant chamber / gate , i think it should be safe enough  since it does not use internally
Thank you guys

If a colloidal siver mix with hydrogen peroxide and turn back into ionic silver, does it still carry posiive charge? AG+
does it still effective ?
thanks

You can't use it for anything due to the contamination of the Ionic Silver with peroxide, so the charge on the ions is not really relevant.
