Determination of arsenic, tungsten, and antimony in natural waters by neutron activation and inorganic ion exchange

Ion exchange on Al/sub 2/O/sub 3/ columns has been used to quantitatively measure As, Sb, and W in water. This procedure requires short thermal neutron irradiations; rapid ion exchange without chemical manipulations, and short ..gamma..-ray counts on a Ge(Li) detector. Precisions of +-5% can be rout...

Zusammenfassung:	Ion exchange on Al/sub 2/O/sub 3/ columns has been used to quantitatively measure As, Sb, and W in water. This procedure requires short thermal neutron irradiations; rapid ion exchange without chemical manipulations, and short ..gamma..-ray counts on a Ge(Li) detector. Precisions of +-5% can be routinely obtained and the following detection limits have been achieved: As, 0.05 ppb; Sb, 0.03 ppb; and W, 0.05 ppb.
