More thoughts on Pt in Ag impurity..... Mike you've got my brain humming now..... Instead of filtering for particles of ammonium chloroplatinate, perhaps a minimum quantity of activated charcoal could be swirled into the solution, presumably the particles would stick to the charcoal. Bright orange on black. Now just get out a high pressure sodium lamp which gives a broad spectrum yellow, close the curtains, and certainly your microscopic particles would stand out like Belisha Beacons.........Certainly?

Thanks John for your input. I am familiar with the orange ammonium chloroplatinate color. Once you have seen it, you will know it. I like your method and will try it. I do believe that the platinum in that form will stay on the filter cellulose. I think we are all glad to hear that comment about the possible non-tested silver in BD's IPM work. After all that time, go over and over your results and then have to say "well maybe the silver was contaminated". Frankly, I would think that it is extremely rare to find PGMs in silver. But I will try the method suggested. mike
