Abstract:
Harmful elements in Egyptian phosphoric acid were identified by radiochemical neutron activation analysis. In the Second Egyptian Nuclear Research Reactor, precipitates were created and examined to identify many types of contaminants (Ce, Co, Cr, etc.). New bionanocomposite materials effectively removed with a high proportion each of Ce, Th, Pa, U, Np, Zn, and Co (100%) and a somewhat lower percentage (65-85%) for Cr, Sc, and Fe from simulated solutions, suggesting promise for purifying phosphoric acid.
