Abstract:
In this paper, aniline and rhodamine are used as materials synthesis probe that can be used to identify copper ions by double changes in absorption and fluorescence spectra. After adding copper ions, the color of the solution can be visually observed to changes from light yellow to red, fluorescence changes from colorless to orange. The fluorescence and UV spectra indicate that the probe exhibits high selectivity and sensitivity to copper ions.
