Özet:

 

A fast, simple, and reliable method for determination of   hexavalent chromium species in soil aqueous and alkaline extracts has been   developed. The procedure is based on the ion-pair extraction of Cr(VI) with   methyltrioctylammonium chloride (Aliquat 336) into xylene. The extract is   analyzed by flame (FAAS) or electrothermal atomic absorption spectrometry   (ETAAS). The method allows the detection of up to 2 mg kg−1−1^{-1} Cr(VI) by   FAAS and up to 25 μμ\mu g kg−1−1^{-1} Cr(VI) by ETAAS. The relative standard   deviation varied in the range 2%-12% depending on the Cr(VI) levels   in the samples. The analysis of certified reference material CRM041-30G   Chromium VI--Soil and spike experiments showed recoveries from 91% to   106%. The procedure was applied to industrially polluted soils.
