Study of Interaction between Gelatin and Copper (Ⅱ) Using Synchronours Fluorescence Spectroscopy

doi:10.7517/j.issn.1674-0475.2005.02.102

Abstract

Abstract: Interaction of gelatin with Cu²⁺ ion was investigated by using the synchronous scan fluorescence spectroscopy. An equation for synchronous fluorescence quenching effect between gelatin and Cu²⁺ ion was introduced. The binding constant and number of binding sites were determined from the experimental data. The change of conformation of gelatin with the addition of Cu²⁺ ion was discussed. The reasonable result were obtained.

Key words: synchronours fluorescence spectroscopy, gelatin, copper (Ⅱ), conformation
