“…Furthermore, it should have pH stability because the process solutions and chemical digestions are, in most cases, very strongly acidic and the change of pH value often leads to undesirable precipitation. PS/DVB is stable over the whole pH range from pH 0 up to pH 14 and there are no changes in the resin's properties up to a radioactive radiation of 106 Gy as proven by an extensive study from DORNOW et al 1 Another important point is the high ion-exchange capacity of Aminex A9 of 2.0 meq/ml, which guarantees a high separation performance even in the presence of a highly loaded ionic matrix.…”

A procedure is described separating, identifying and determining the actinides (An) U, Np, Pu, Am and Cm in the presence of the lanthanides (Ln) La, Ce, Pr, Nd, Pm, Sm, Eu and Ho on an analytical scale. It is based on high-pressure liquid chromatography (HPLC) combined with a dual on-line detection system and is accomplished within a short time, in one step and under isocratic conditions (for An). The separation was carried out on a strongly acidic and highly capacitive cationic exchange resin on a polystyrene divinylbenzene copolymer (Aminex A9, co. BioRad) basis. Radionuclides emitting c~-and [3-particles are detected on-line using a custom-made solid scintillation flow-through cell. Inactive components are monitored by colour reagent complex detection (Arsenazo III, ,% 648 nm) with a VIS detector placed in series.
