Substoichiometric determination of silver by Neutron Activation Analysis

A rapid and selective method has been developed for the determination of Ag in biological samples and mineral ores by thermal neutron activation analysis employing substoichiometric extraction with 1,2,3-benzotriazole /1,2,3-BT/ into chloroform. The time required for the radiochemical purification and counting of two samples was 1 h. 4.84 g Ag can be determined with an accuracy of 7.44% and a precision of 3.57%.
