  Spectral Analysis and Determination of Palladium II Based on the Environment-Friendly and Water-Soluble Polymer

  摘要：

  The environment-friendly and water-soluble polymer was prepared via ring-opening reaction between polyvinyl alcohol (PVA) and 3-epoxypropoxy fluorescein (EPF). Based on the quenching of fluorescence signals of PVA-EPF in the 520nm wavelength and relative quenched intensity is good linear with the concentration of palladium II. A simple, rapid, sensitive, and specific detection method for palladium II is proposed. In comparison with traditionary methods, the present method is environment-friendly, stable, easy to operation, more water-soluble, and cheaper. The results suggested that PVA-EPF may offer potential as a reusable polymer sensor for palladium II ion in aqueous solution.
