Your posts are very polite and friendly. I should have responded to your last post, but I started getting headaches again and could not help. From what I recall, you may have descided to abandon the stainless steel cathode and huge anode. Another approach that might help get you started would be to make two electrodes shaped in a "W" that fit inside a 1/2 litre drinking glass. If you have not already bought the silver wire, 12 ga has a bit more area and is stiffer than 14 ga., but 14 ga would work if you already have it. The biggest problem if trying to make the cs too quickly. I believe you have 35V or 40V available, which helps considerably. You will need to make the unit and fill it with dw, then measure the initial voltage across the cell when voltage is first applied. You can use a 100k series resistor for the first reading then just calculate the unknown using standard voltage divider equations. You have to work fast. The cell resistance drops quickly as soon as ions enter the solution. Once you know the initial cell resistance, you can start by making the series resistor the same value. As the conductance of the cell increases, the current will also increase. But it will be limited by the series resistor and you won't have problems with the exponential runaway that normally occurs with a constant voltage source. Let it run until you start getting oxide or sludge on the electrodes. This tell when tyou have pretty much reached the maximum concentration of ions for your configuration. Measure the current at intervals, then integrate the current vs time curve in WPlot to get the average. Toss that in Mercury to see how much silver was liberated. You have to account for the visible deposits, and also the oxide particles that are too small to see. This will reduce the ppm from the calculated value. A Hanna PWT can be used to confirm your measurements and calculations. You can improve the system by looking for good quality dw that gives the highest ppm value, and by changing the series resistor to control the average current density. You can check the archives for more information. I just did something very stupid in Windows, and if I don't stop now I will destroy my desktop. Sorry - Bye! Good Luck!
