The reason that I am doing this is because the type you get at the hardware store for cleaning drains has a fair amount of impurities in it. The stuff I got has about two perc…Copper - Essential Chemical Industry,Figure 6 Purification of copper by electrolysis. The ions migrate to the cathode, are reduced to pure copper and deposited on the cathode. From time to time, the pure copper is scraped off the cathode. Many impurities from the copper anode, such as gold, silver, platinum and tin, are insoluble in the electrolyte solution and so do not deposit on the cathodes. Instead, they are deposited as,GMP automated purification of copper-61 produced in,,Copper-61 is a positron emitter with very favourable physical (61.5% β+, 1.22 MeV max.) and chemical properties that is emerging as a promising PET imaging agent.
