Determination of some trace elements in mineral spring waters by total reflection X-ray fluorescence spectrometry (TXRF)

Trace metal concentrations of mineral spring waters in central Anatolia, Turkey were investigated by total reflection X-ray fluorescence spectrometry (TXRF). The concentrations of trace heavy-metal ions were quantitatively determined with an internal Ga standard. The element concentrations obtained by TXRF are comparable to results obtained by graphite furnace absorption spectrometry (GFAAS) after separation-preconcentration on an Amberlite XAD-4 column and inductively coupled plasma-mass spectrometry (ICP-MS).
