ANALYTICAL METHODS FOR IMPURITIES IN CESIUM METAL.
Abstract
Methods were developed and tested for the determination of oxygen, nitrogen, and carbon in cesium metal, in concentrations of from less than 10 to more than 300 parts per million. In general the methods appear to be free from interferences. Oxygen is the only impurity likely to be found in more than extremely small traces in high quality cesium metal. The determination of oxygen can be carried out by the nondestructive neutron activation method, newly developed to give sufficient sensitivity, or by a new modification of the butyl bromide method designed to improve the accuracy. Previously the latter procedure gave low results, demonstrated in the present work to have been caused by a reaction between cesium oxide and butyl bromide. The methods developed for nitrogen and carbon permit identification of the forms in which these elements are most likely to occur, even though their concentrations are in the order of only 5 ppm.
