ABSTRACT
Two preconcentration procedures for electrothermal atomic absorption (ETAAS) determination of thallium in mineral, spring, tap, river, underground and sea water were developed and compared: (i) Column solid phase extraction with new sandwich type disposable sorbent columns (CSPE) and (ii) Filtration of thallium dithiocarbamates through a Millipore filter of 0.45 mm pore size followed by dissolution of the filter + precipitate in IBMK (PP) and introduction of the obtained organic slurry into the graphite furnace. With addition of indium as sorption and precipitation collector enrichment factors of 100 (CSPE) and 200 (PP) were achieved.
