A procedure for simultaneous determination of arsenic, cadmium, copper, tin and zinc in beef extract by neutron activation analysis

Abstract

A radiochemical procedure developed by the authors for neutrón activation analysis of As, Cd, Cu, Sn and Zn in beef extract samples is described, based on combined precipitation steps to isolate the elements to be determined. Nuclides aie separated with high degree of purity and good chemical yields. Interferences from threshold reactions are discussed and calculated. Results are shown for analysis of six samples.
