The paper presents the results of aluminium determinations in ground water samples of the Miocene aquifer from the area of the city of Poznań (Poland). The determined aluminium content amounted from <0.0001 to 752.7 μg L(-1). The aluminium determinations were performed using three analytical techniques: graphite furnace atomic absorption spectrometry (GF-AAS), inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). The results of aluminium determinations in groundwater samples for particular analytical techniques were compared. The results were used to identify the ascent of ground water from the Mesozoic aquifer to the Miocene aquifer in the area of the fault graben. Using the Mineql+ program, the modelling of the occurrence of aluminium and the following aluminium complexes: hydroxy, with fluorides and sulphates was performed. The paper presents the results of aluminium determinations in ground water using different analytical techniques as well as the chemical modelling in the Mineql+ program, which was performed for the first time and which enabled the identification of aluminium complexes in the investigated samples. The study confirms the occurrence of aluminium hydroxy complexes and aluminium fluoride complexes in the analysed groundwater samples. Despite the dominance of sulphates and organic matter in the sample, major participation of the complexes with these ligands was not stated based on the modelling.
本文介绍了波兰波兹南市区中新世含水层地下水样本中铝的测定结果。测定的铝含量从<0.0001 到 752.7μg/L 不等。铝的测定采用了三种分析技术：石墨炉原子吸收光谱法（GF-AAS）、电感耦合等离子体原子发射光谱法（ICP-AES）和电感耦合等离子体质谱法（ICP-MS）。对特定分析技术的地下水样本中的铝测定结果进行了比较。结果用于识别该地区断裂地堑中生代含水层向中新世含水层地下水的上升。使用 Mineql+程序，对铝及其以下铝配合物：与氟化物和硫酸盐的羟基进行了发生情况的建模。本文介绍了使用不同分析技术进行的地下水铝测定结果，以及首次在 Mineql+程序中进行的化学建模，该建模能够识别研究样本中的铝配合物。该研究证实了在所分析的地下水中存在铝羟基配合物和铝氟配合物。尽管硫酸盐和有机物在样本中占主导地位，但根据建模，并未表明这些配体的配合物有主要参与。
