Re: ion particle ratio

-OK, now this is where you can put me right maybe. As I don't observe any settlement in the bottom of my containers would you agree that the solution I have is still a good result? By this I am referring to the particles, or particle clusters, being of suitable size as to still be bio-available if no settlement is observed after suitable stabilising time frame, (and solution remaining clear). Would you consider this to be a fair statement, as broad as it may be? I am going on the assumption that if all silver remains in solution, with no visible settlement, and the solution remains clear, then this can be considered a good CS solution...Yes/No?


JAB

A close definition of a colloid solution is particles suspended in water that are too small to settle out. So it sounds like that is what you have unless you don't actually have any silver in the water at all. And if your solution was beginning to get larger particles the color you would first see would be a light yellow. And yellow is still good enough. I wouldn't mess with filters unless you had visible particles in the bottom or floating on top. end


-You may be right there about the testing elsewhere. I believe I have recently discovered what is going on here though. I have a diode, (LED), and resistor in the circuit and as a consequence of the diode the current will not flow the opposite way when switching electrodes, this I now consider is resulting in ions of silver being 'sintered' off one electrode but as they are unable to 'gravitate' to the other electrode the ions are floculating or agglomerating around this particular electrode resulting in larger particle clusters being formed which are slowly distributing themselves throughout the water. Primative method of descriprion I know, and if you can follow this would you think this is a fair assumption? I can get past the diode issue, by simply removing it from the circuit.


JAB

I think you might be using AC for some reason? If so the diode would make it pulsed DC which shouldn't be a problem and might help. All the sludge will collect on one electrode and if you reverse the current it will likely go into the solution. Sounds like you might want to stir the fluid though to keep the ppm from getting too high around the electrodes.

Just use a simple wall transformer to get a DC voltage and then use a 20 mA miniature light bulb in series to limit the current. The bulb should have a voltage rating close to the DC output. When the bulb starts glowing you have an indicator that the current is getting higher but it will only go to 20 mA at the most, which is still a low enough current. Tweet
