Simultaneous determination of iodine and bromine in urine by neutron-activation analysis

Abstract

Neutron-activation analysis was used for the simulataneous determination of iodine and bromine in urine. The activated iodine and bromine were separated by radiochemical methods. The 0·46 MeV and 0·55 MeV peak areas of ¹²⁸I and ⁸²Br, respectively, were measured by means of a multi-channel analyser. The amounts of iodine and bromine were found to be of the order of 10^–7 and 10^–6 g ml^–1 of urine, respectively, for normal human beings of different ages.
