摘要：

An anion-exchange scheme has been developed for the preconcentration and almost specific separation of microgram and sub-microgram amounts of thallium. It is used in conjunction with a fluorimetric method based on rhodamine B for the determination of 0.1-6 p.p.m. of thallium in silicate rocks and sediments. The method showed a coefficient of variation of 1.2% at the 6 p.p.m. level. A procedure is also described for the determination of thallium in natural waters in which the element is concentrated by anion exchange and determined by neutron activation. A sample of water from the Irish Sea was found to contain 18.7 ± 0.9 ng Tl/1. © 1969.
