purifiion of copper by electrolysis metal extraction …

Such plants cannot always get rid of the copper ions and they build up in leaves. These plants naturally absorb copper compounds through their roots as they feed on the nutrients around them and because they can''t always get rid of the excess of certain metals like copper, this results in higher concentrations of these copper compounds in the plant tissues e.g. leaves.
