WebApr 24, 2024 · Pulsed electrowinning at 2.0 V with periods ranging from 1 ms to 10,000 ms was successful in lowering the Ag and Au concentrations of the solution below 1 µg/mL in the most favorable circumstances. Pulsed electrowinning at 2.5 V was also effective in removing Ag and Au from solution, but apparently offered no advantage over a 2.0 V pulse.
