Description

A procedure for the separation and recovery of arsenic radionuclides from a germanium oxide target using a liquid-liquid extraction technique is described. The effects of target material and preparation were investigated. The effects of hydrochloric acid and hydrogen peroxide concentration on germanium recovery were determined. The efficacy of various reducing agents were evaluated for recovery of arsenic. In addition, the effects of hydrochloric acid and reducing agent concentration were evaluated for optimum arsenic extraction conditions. The germanium oxide target material was recovered in greater than 99% radiochemical yield with less than 1% crossover contamination of germanium radionuclides. (author)
