Abstract:

A new polyglycerol phthalate extractant was prepared and characterized using Fourier transform infrared spectroscopy, proton nuclear magnetic resonance (1H NMR) spectroscopy, and thermogravimetric analysis. A preliminary study of the extraction of long-lived (90Sr and 152+154 Eu) and short-lived (90Y) radionuclides by polyglycerol phthalate was performed. The influence of different diluents, concentration of the acid, type of acid, and various interfering ions was explored. The stripping of 152+154 Eu radionuclide was studied by using different acid solutions, and it was found that sulfuric acid was the ideal acid for this purpose. Furthermore, 152+154 Eu was extracted from the fission products (90Sr) and the extraction% of 90Sr was found to improve in the presence of interfering ions.
