| Abstract: | Extracting the free copper in phthalocyanine pigment with diluted sulfuric acid,in weak alkaline conditions,Cu2+, and diethyl dithiocarbamate sodium react quantitatively to generate a yellow complex which insoluble in water but soluble in chloroform. The complex can absorb quantitatively 440nm wavelength of light. Then,according to the size of the absorbance to determine the solution concentration of copper ions. |
