    Purification an overview | ScienceDirect Topics

    The purification amount (PA or q) was defined as the amount of contaminants (in micrograms) removed by SW by comprehensive effects including dilution of the wetland water, closure and absorption of the Sphagnum, microbial action, and adsorption to the peat and cobble. The unit of PA could be mg cm− 2 when SW area was considered.

    The Reaction of Aluminum to Copper in Electrolysis ...

    Electrolysis has many practical and industrial applications. For example, it is used to purify aluminum. In this case, the aluminum is obtained from an ore called bauxite. The electrolytic cell used in this process typically does not involve a copper anode. Instead, the anode is usually made of carbon. Electrolysis is also used in electroplating.
