Synthesis of maghemite nano-particles and its application as radionuclidic adsorbant to purify 109Cd radionuclide
Maghemite nano-particles were synthesized by a solid-state chemical reaction for its highly selective use as, cyclotron-produced, 109 Cd (462.9 days) purification method of choice. 109 Cd radiochemical separation starts with Ag activities precipitated with HCl 0.0015 M followed by, on a second step,...
