Crucible atomizer for the determination of
dissolved and suspended elements forms in natural waters
Abstract
For electrothermal atomic absorption
analysis of natural waters a model of the specialized crucible
atomizer-microcolumn has been proposed and tested, in which the zone of
selection of suspended matter and the zone of dynamic preconcentration of
dissolved forms of elements are separated. Independent direct analysis of solid
suspended matter and DETATA-concentrate is possible after completion of
preconcentration. Such approach is used for determination of suspended and
dissolved forms of cadmium and lead in river and soil-ground waters.
Key words: electrothermal atomic absorption
analysis, natural water samples preparation, crucible atomizers.
