With accurate current control with no ramp up and making a very highly soluble solution, Faraday calculations to predict PPM should be spot on.

Tony, I don't think that 1mA/ sq inch is high. In fact, I think you can use higher currents since the citric acid molecule captures the silver ions as they enter the solution and you won't have much of a problem with agglomeration. Mostly I was thinking about the calculation of ppm and knowing the current. Also, if your current limiter is low power, realize that the higher conductivity of the solution means that for a given current, there will be more voltage dropped across the limiter and that could be a problem for a limiter with a marginal power dissipation capability. Also, with a low current, getting to a high ppm, if that is your goal, could take a long time. - Steve N -----Original Message----- From: Tony Moody [mailto:[email protected]] Sent: Thursday, May 21, 2009 12:41 PM To: Norton, Steve Subject: Re: CS>Use of high ppm CS Hi Steve, Thanks a lot for the recipe. Yes I have citric acid here. its the cooking grade but for me that should be OK. My silver setup is current controlled and fixed at close to 1mA/ sq inch, which may be a bit hectic. I should be able to turn current down from there by fitting a variable resistor. Many thanks, Tony Moody -- The Silver List is a moderated forum for discussing Colloidal Silver.
