Abstract
A method for the extraction-spectrophotometric determination of copper with PAN is developed. This method differs from the existing approaches in selectivity, sensitivity, simplicity, and rapidity. It is recommended to analyze ores, concentrates, industrial solutions, and wastewater, as well as materials of complex chemical composition without the separation of accompanying ions directly in the organic phase.
