Abstract

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 \\upmu \g L. 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.
