title: Determination of Co, Cu, Fe, Ga, W, and Zn in rocks by neutron activation and anion-exchange separation.
abstract: A neutron-activation method for the simultaneous determination of cobalt, copper, gallium, iron, tungsten and zinc in rocks is described. The method is based on anion-excbange separation in hydrochloric acid media. Chemical yield is higher than 97% for all elements, except for tungsten, where the recovery of the carrier is established by re-activation. The precision is about 1-3% for the iron determination and about 3% for cobalt, copper, gallium and zinc.
