Description: In the process of spectrophotometric analysis of trace cobalt ion concentration in high concentration zinc solution, the base ion Zn(II) and the test ion Co(II) have similar chemical properties, and the base ion concentration is too high, resulting in Co(II) The spectral signal overlaps with the spectral signal of Zn(II), and the absorbance and concentration of the solution show strong nonlinearity and poor additivity over part of the wavelength band. Therefore, trace Co(II) concentrations cannot be achieved through the full band information. The test. In this paper, the interval-correlation method is proposed to screen the UV wavelength of the solution
