Reid Hi Reid, I'm not sure if Ken really said that you could never exceed a ppm of 26 due to the _inavailability_ of hydroxyl ions. The problem is there are _too many_ hydroxyl ions. The hydroxyl ions form at the cathode when hydrogen ions accept electrons and form hydrogen gas. Then the hydroxyl ions combine with the silver ions to form oxides, which limits the ppm. I posted the equations in previous replies. I'm not sure if those PPM readings can be relied on. Those numbers really sound strange to me. Can you post a link to your description of the 110VDC system? If you are really getting 50 ppm, you can do a simple salt test to verify this. Pour about 1 inch in a glass and add two or three shakes of salt. When the salt dissolves, the silver ions combine with the chlorine ions to form silver chloride, which precipitates out as a white solid. At 50 ppm, you should get a milky white dispersion similar to skim milk. You should not be able to see any objects behind the glass. How did you arrive at the 50 ppm number? I thought you were trying to make oxides, presumably because they are larger and would have a better chance of getting trapped in the ceramic. Wouldn't any ions simply wash out when water passes through the filter? And what happens if the filter dries out during storage or shipment? The ions would convert to oxide anyway as the water evaporated. Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
