May 01, 2019· Fig. 1 shows the absorption spectra of zinc (20 g/L), cobalt (0.3 mg/L), copper (0.5 mg/L) in the range of 250600 nm. As can be seen from Fig.1, the signal of zinc is much larger than the signal of each trace ion, resulting in lowconcentration ion signals of cobalt and copper masked by highconcentration zinc signal, and the absorbance of zinc is close to absorbance of their mixture.
