Journal ArticleDOI
Determination of Arsenic(III) and Total Arsenic(III,V) in Water Samples by Resin Suspension Graphite Furnace Atomic Absorption Spectrometry
TL;DR: A preconcentration method of arsenic using ammonium pyrrolidinedithiocarbamate (APDC) and a finely divided anion-exchange resin is described for the determination by graphite-furnace atomic absorption spectrometry (GFAAS) as discussed by the authors.
Journal ArticleDOI
Determination of Phenol in Tap Water and River Water Samples by Solid-Phase Spectrophotometry
TL;DR: In this paper, a solid phase spectrophotometric method for the determination of phenol in tap water or river water samples was developed, where the antipyrine dye formed by the reaction between phenol and 4-aminoantipyrine was extracted and concentrated from 50 cm 3 of sample solutions on the finely divided anion exchange resin in the presence of sodium sulfate as the salting out reagent.
Journal ArticleDOI
Determination of Cadmium and Lead in Tap Water by Graphite- Furnace Atomic Absorption Spectrometry after Preconcentration on a Finely Divided Ion-Exchange Resin as the Pyrrolidinedithiocarbamate Complexes
TL;DR: In this paper, a method based on the combined use of ammonium pyrrolidinedinedithiocarbamate (APDC) and a finely divided anion-exchange resin has been described for the determination of trace amounts of cadmium and lead by graphite-furnace atomic absorption spectrometry (GFAAS).
Journal ArticleDOI
Enrichment of trace amounts of copper as chelate compounds using a finely divided ion-exchange resin
TL;DR: In this paper, the enrichment of trace amounts of copper as complexes with various chelating agents was examined with the use of finely divided anion-and cation exchange resins of the macroreticular type.
Journal ArticleDOI
Determination of V(IV) and V(V) by electrothermal atomic absorption spectrometry following selective solid-phase extraction and the study on the change in the oxidation state of vanadium species in seawater during the sample storage.
TL;DR: The changes in the oxidation state of vanadium in artificial and natural seawater samples were studied by electrothermal atomic absorption spectrometry (ETAAS) with a direct injection of a resin suspension using a suspension of an anion-exchange resin and determined by ETAAS independently.
