Abstract
A selective and sensitive extraction-photometric method for the
determination of copper (II) with PAN has been developed. This method is recommended
for the determination of copper in ores, concentrates, waste and industrial solutions and
other materials of complex chemical composition without prior separation of associated
elements.
