Abstract
In order to explore more functional supported probe material, the ultraviolet absorbance together with fluorescence properties of a probe with the structure of salicylaldehyde Schiff-base in various solvents and pHs were investigated after its synthesis. When the concentration of Cr3+ ion was in the range of 3~7×10-5 mol•L-1, the complex reaction between the probe and Cr3+ could be used for quantitation of the latter, which was developed by UV absorbance intensity of the complex and the concentration of Cr3+ ion. Ultraviolet analytic results determined that they were complexed in the molar ratio of 1:1. Finally, the MOF-supported probe material was successfully synthesized for further application, which realized the immobilization of the probe through simple operations.
