Abstract:Highly concentrated copper in electrolyte was determined automatically and rapidly by a spectrophotometry based on the color of the hydrated copper ion. The interference of turbidness which is caused by thiourea and bone glue was corrected by dual-wavelength measurement. The interference of SO2-4was corrected by adding H2SO4to the standard solution. The hydrated nickel ion interferes in the determination of copper because it is green. NiSO4was added to the standard solution in order to eliminate this interference, since the content of nickel in copper electrolyte is relatively constant. The method has been used successfully at Guixi Smeltery. Loading frequency of 240 samples per hour was obtained.
