Radiochemical thermal neutron activation analysis of fish solubles

A rapid and simple method has been developed for the determination of Mn, Zn, Cr and Ag by radiochemical thermal neutron activation analysis, involving solvent extraction and precipitation technique. Mn, Zn, Cr and Ag can be determined with an accuracy of 8.9, 5.8, 7.7 and 7.6%, respectively. The method has been employed for determination of the elements in fish solubles. Two samples and a standard can be analyzed in three hours.
