Covering power, throwing power, polarization value, polarizability, peak point potential and peak point current of the brightener are also almost equal to those of the abroad counterparts.

Cyclic voltammetry was also used to study the effect of content of cupric ions and arsenic ions on peak current density and peak potential of cyclic voltammetry graphs of copper electrodeposition.

The ECFC, in which experimental parameters (a shift in a peak potential and a variation in a peak current) are included, appears to be a characteristic function for a particular metal ligand system.
