| Abstract: | With PAR as the colour-developing agent, the colour conditions and incident ray wavelength of Cu2+ , Zn2+ in the solution of pyrophosphate imitating gold are determined by double-wavelength spectrophotometry. The influence and discharged measures of interference elements are discussed and linear range and determining method are given. |
