Neutron Activation Analysis Methods for the Group Viii Elements

Nucleonics

“…Thompson and coworkers (951) give good flow sheets for the systematic analysis of many elements in this ultrapure material. An article by the Chalk River group (468) discusses activation analyses of interest to atomic energy programs, while the Oak Ridge group describes analysis of reactor materials (553), methods for the Group VI11 elements (642) , and the determination of trace elements in water (99, 100) by neutron activation analysis.…”

“…Two other authors (642,1012) utilize the 102-minute half life of cobalt-6Om for determination of cobalt in reactor materials. The presence of manganese requires a rapid srparation for the cobalt which can be achieved in 30 to 40 minutes and still alloms a sensitivity limit of 1 to 2 y.…”

“…Italian workers have determined the iridium content of very pure platinum by two different activation techniques (9), while Miller (642) has utilized the shorelived platinum isomer for this type of determination. Gibbons (337) reviews the determination of gold in biological materials and reports as little as 10-10 gram of gold can be determined with an accuracy of about 2%.…”

“…Molybdenum, Silver, Indium, and Antimony. Bowen (110) determined 0.1-7 amounts of molybdenum in biological materials, while short-lived isotopes of Group VIII elements such as rhodium and palladium have been used by Miller (642) in analyses by this method.…”

“…Zvyagintsev and Kulak (1058) discuss the determination of gold and the platinum metals in refined silver and cathode nickel by activation analysis. Italian workers have determined the iridium content of very pure platinum by two different activation techniques (9), while Miller (642) has utilized the short-lived platinum isomer for this type of determination.…”
