title: Ion-exchanger phase absorptiometry for trace analysis.
abstract: Ion-exchanger phase absorptiometry is based on the direct measurement of the degree of light-absorption by an ion-exchange resin phase which has sorbed a sample component. Direct application of the method makes it possible to determine trace elements in natural water samples without preconcentration. In this paper, all systems hitherto developed are reviewed and the theoretical background of solid-phase absorptiometry is described.
