Hi. Just dropping a quick note to say hello and get off to a bad start
by asking awkward questions....
I've been playing with simple "colloidal" silver makers based on .999
silver rods with a single PP3 9V cell and a resistor and high
sensitivity LED in series. I've had to make do with tap water since
getting distilled water is surprisingly difficult in Scotland where our
tap water is one of the purest available, and thus bottled water has the
same status as a bottle of cola. (Just a handy drink.)
The results have been the fine mist of ionic silver and the inevitable
darkening of the fluid over time as the ionic silver bonded with the
tiny amount of chlorine and nitrates present in the water.
Last night I stumbled across the technique of using AC to make a less
ionic solution and promptly built a new version that is powered by a
24Vac wall wart connected to the electrodes via a 1k resistor and two
LEDs in inverse parallel so they both light on the AC and don't rectify
the supply.
I left it on all day today and the water shows no sign of the usual
misting from the electrodes and has remained absolutely clear. A test
with the resistive style dissolved solids tester showed that water from
the tap had 40ppm impurities while the treated water was identical.
Hmmmm.
A test with a fairly high output green laser showed fresh water had
little absorption, but the treated water had quite a strong line and
sparkle to it suggesting that there is some form of silver going into
the liquid.
Is 50Hz too high a frequency for the preparation of colloidal/ionic
silver?
Any comments would be appreciated.
I wish there was an easy way to get a genuine measurement of the amount
of colloidal and ionic silver present in a solution.
