I used to sell a unit like that several years ago. NO > sludge. > "Ole Bob" Robert, The Faraday equation works fine. It tells you how much silver was liberated. Then you measure the ppm, and find out why there is a difference. The 12 ga wire seems to go to 22 pm before making noticeable sludge. The salt test shows a very strong dispersion. So I was very surprised at the ppm numbers you measured, but the salt test confirmed them. The salt test is also a very good way to compare two samples. If you pour some cs into another glass and add a few drops of H2O2, any silver oxide is converted to ions. If you do a salt test, you can compare the dispersions with and without the H2O2 added. If they are the same, it tells you very little cs is in the form of oxide. The Hanna PWT may give unreliable readings with H2O2, so it might not give as good results. Now, there is no question your cathode arrangement causes very high current density, which explains the black deposits on the third run of your test. That was the only run where you mentioned any deposits. Since the deposits remain on the electrodes, adding H2O2 to the cs may not show much difference. But the Faraday equation showed a significant loss, so it is an important diagnostic tool. Similarly, although there were no deposits on the parallel plate runs, your measurement and the salt test both agreed the ppm was quite low. Again, the Faraday equation shows there was a significant loss, most likely due to the formation of oxide particles in the space between the plates. H2O2 might have helped clarify this. So the Faraday equation is a bit like Ohms law in electrical circuits. You know much you put into a system, and measuring the ppm tells you how much you got out. You can optimize the process by minimizing the difference. The Faraday equation is a very important tool. Now that you have Mercury, the calculations are easy. The salt test is a good sanity check, and should be included with the ppm measurement. Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
