Abstract
AbstractA systematic study on the purification of Rubidium‐86 was carried out. Ten grams of rubidium chloride was irradiated in the THOR for 120 hours at the neutron flux of 3×1012 n/cm2‐sec. After the anionic species induced by nuclear reactions were removed by anion exchange resin, the trace amount of cesium contaiminated in the irradiated target was separated from rubidium‐86 by ion exchange method. Dowex 50w×4(200–400 mesh) was used as the exchange resin and dilute hydrochloric acid of varying concentrations was employed as the eluant. Optimum conditions for separating a large quantity of rubidium‐86 from the trace amounts of cesium‐134 was investigated by varying column ratios, hydrochloric acid concentrations and flow rates. An inorganic exchanger was also tried for comparison.
