The article presents the hyphenated technique of high performance liquid chromatography and hydride generation atomic absorption spectrometry (HPLC-HG-AAS) in determination of antimony inorganic species: Sb(lII) and Sb(V) in ground water samples. While carrying separation of these forms on an anion-exchange column in a cliromatographic system and detection by means of hydride generation atomic absorption spectrometry method, the analytical signals of the determined forms were separated at the detection limits of 6.8 ng/cm' (peak high) or 2.7 ng/cm' (peak area) in the case of Sb(lll) and 4.8 ng/cm3 (peak high) or 3,2 ng/cm' (peak area) in the case of Sb(V) with RSD below 20% at the concentration of 25 ng/cm'. The hyphenated technique was applied for antimony determinations in polluted ground water.

W artykule przedstawiono technikę łączoną wysokosprawnej chromatografii cieczowej z detekcją absorpcyjnej spektrometrii atomowej z generowaniem wodorków (HPLC-HG-AAS) w oznaczeniach specjacyjnych nieorganicznych form antymonu: Sb(III) i Sb(V) w próbkach wód. Prowadząc rozdzielanie form specjacyjnych na kolumnie jonowymiennej w układzie chromatograficznym i detekcję z użyciem absorpcyjnej spektrometrii atomowej z generowaniem wodorków uzyskano rozdzielenie sygnałów analitycznych oznaczanych form antymonu przy granicach wykrywalności 6,8 ng/cm3 (wysokość piku) lub 2,7 ng/cm1 (powierzchnia piku) Sb(III) i 4,8 ng/cm' (wysokość piku) lub 3,2 ng/cm' (powierzchnia piku) Sb(V) z RSD odpowiednio poniżej 20% dla stężenia 25 ng/cm'. Technikę łączoną zastosowano w oznaczeniach antymonu w zanieczyszczonych wodach podziemnych.
