Mike, Thanks for the input. The 2400 ppm silver citrate is a concentration sold by Bioscience. They are the ones generating the silver citrate by electrolysis and advertizing the antibacterial spray used in the prison. My wife talked to the gym owner about using the silver citrate as an antibacterial spray to protect against transfer of infections between gymnists. She is very interested. What she uses now is very toxic and expensive. When telling about the non-toxity of silver the owner was shocked when told I drink the solution! She will use the silver but wants to use the Bioscience product so I will be getting more info on purchasing the 2400 ppm concentrate. I haven't had time to really play with the silver citrate. The 400 ppm solution still shows no signs of precipitation. I had diluted some of the 400 ppm to 20 ppm. The 20 ppm did precipitate out over night. There sure is a lot of silver in the solution even though it does not show when in solution/suspension! I think the 20 ppm precipitated because the citric acid concentration was below some min concentration needed to keep the silver as silver citrate. I plan on finding just what the min concetration of citric acid is. The solution definately has some tartness. I have a pool pH test kit somewhere but I will need to track it down. I have no problem taking the solution as is but do wonder if a low or high pH solution can inhibit ingestion of the silver citrate. When I was making the silver citrate, I was astonished to see hot the citric acid absorbed the silver with very little silver oxide forming on the negative electrode. I kept checking that there really was 650 ma current - using multiple meters to verify it. At some point I intend to use the method using silver oxide as the silver ion source. I will let you all know what I learn. - Steve N

Are you thinking about Microdyne, here, Stever?

I'll make a wild guess: If you ran 'til you saturated and it started to precipitate, you'd get an idea of how much silver a given volume/concentration can absorb. Any current would probably let you get to the same concentration, with the only variables being how long it takes and whether you boil the water! You could maybe even calculate the amount you could get based on the chemical reaction between the silver and citrate. This reminds me of the old days, making CS with 3 9v batteries and a drop of brine solution as a "starter" and getting an alleged "1 ppm per minute" while streams of bubbles came off the negative electrode and visible clouds of "silver" (silver chloride, I presume) came off the positive. Definitely not an exercise in current limiting. > * Do I need to balance the pH to something closer to 7.0 after > generation? What is the pH? Got test strips?
