I don't know what they mean by "commercially attainable?" We can get silver from scientific materials supply companies like Alpha/Aeser or Aldrich that go up to 5 or 6 nines, easily. It's not cheap, but silver is evidently not that hard to refine. Stuff like that is used in all kinds of scientific applications where ultra-purity is needed. Fortunately, even 3 nines (99.9%) purity is adequate for making CS in the 10 ppm range, as any impurities from the anode metal ought to be less than 10 parts per BILLION. Which means that impurities in your water ought to be more significant. Four nines is available and not much more expensive than 3 nines, if you feel you need the peace of mind. Be well, Mike D.
