| Abstract: | A radiochemical neutron activation method for the simultaneous determination of arsenic, cadmium, cobalt, mercury, molybdenum, and zinc in fresh water is described. The method is based on anion-exchange separation in hydrochloric acid media followed by simple precipitations. The determination limits, based on analysis of a 5-ml sample without preconcentration, and with a well-type NaI(Tl) detector, are as follows: As, 10-3 μg l-1 ; Cd, 6 × 10-2 μg l-1 ; Co, 4 × 10-3 μg l-1 ; Hg, 7 × 10-3 μg l-1 ; Mo, 10-1 μg l-1 ; Zn, 2 × 10-1 μg l-1. The method is adequate for the analysis of natural fresh waters. |
