    Determination of inorganic arsenic species As(III) and As(V) by high performance liquid chromatography with hydride generation atomic absorption spectrometry detection

  • Original language description

    The paper presents the principles and advantages of a technique combining high performance liquid chromatography and hydride generation atomic absorption spectrometry (HPLC-HGAAS) applied to speciation analysis of inorganic species of arsenic As(III) andAs(V) in ground water samples. With separation of the arsenic species on an ion-exchange column in the chromatographic system and their detection by the hydride generation atomic absorption spectrometry, the separation of the analytical signals of the arsenic species was excellent at the limits of determination of 1.5 ng/ml As(III) and 2.2 ng/ml As(V) and RSD of 4.3% and 7.8% for the concentration of 25 ng/ml. The hyphenated technique has been applied for determination of arsenic in polluted ground water in the course of the study on migration of micropollutants. For total arsenic concentration two independent methods: HGICP-OES and HGAAS were used for comparison of results of real samples analysis.

    Stanovení anorganických specií arsenu As(III) a As(V) vysokoúčinnou kapalinovou chromatografií s detekcí atomovou absorpční spektrometrií s generací hydridu

  • Czech description

    Článek se věnuje principům a výhodám techniky spojující vysokoúčinnou kapalinovou chromatografii s detekcí atomovou absorpční spektrometrií s generací hydridu (HPLC-HGAAS) aplikované na speciaci anorganických forem arsenu As(III) a As(V) v podzemních vodách. Při separaci specií arsenu na iontově-výměnné chromatografické koloně s detekcí HG-AAS bylo dosaženo výborných mezí stanovení 1.5 ng/ml pro As(III) a 2.2 ng/ml pro As(V) a relativní směrodatné odchylky 4.3% a 7.8% pro koncentraci 25/ng/ml. Technikabyla použita pro studium migrace arsenu jako mikropolutantu v znečištěných podzemních vodách. Pro stanovení celkového obsahu arsenu byly pro srovnání použity dvě nezávislé metody: HGICP-OES a HGAAS.
