Abstract
Abstract Neutron-activation analysis has been applied to the determination of traces of silver in specimens of galena and blende. Use has been made of the radionuclides 110m Ag- 110 Ag. The radiochemical separation after the addition of carrier has been based mainly on precipitations of silver as chloride, sulphide, oxide, and iodate. Radiochemically pure silver was finally precipitated and counted as the iodate; the chemical yield was determined gravimetrically. In order to avoid errors due to self-shielding, standards were made by adding small known amounts of silver to analytical samples. I'recision (standard deviation) of the radioactivation analyses has been better than ± 3%, in all cases.
