Abstract

Rare earth elements (REEs) were detected and determined (except Eu, and in some cases Gd, Tb and Tm) in three Hungarian wine samples - Királyleányka, Blauer Portugieser and Merlot (2004 vintage) - from the Eger viticulture area by double focusing inductively coupled plasma sector field mass spectrometry (ICP-SF-MS) in low resolution mode (R = 300). The REE average concentrations of the samples determined after microwave-assisted digestion were in the pg cm- 3 concentration range. According to the results, among these grapes grown on volcanic slopes, the REEs uptake by the Királyleányka and Blauer Portugieser seemed to be more inhibited. Four, commercially available bentonite samples - fibrous (Gelbenton), protein containing (Evergel), and two Na bentonites (BW200 and Tükrös) - were used for wine clarifying. Gelbenton altered the less the REE concentrations of the wine samples. The lowest increase (1.1-1.5 times) was established for the Merlot red wine sample.
