Abstract: “Nano TiO2 were applied to preconcentration and determination of Pb (II) in water samples using hollow fiber based solid-liquid phase microextraction (HF-SLPME) combined with flame atomic absorption spectrometry (FAAS). The effect of experimental conditions was investigated. The method was linear in the range of 0.6 -3000 μgmL-1. The relative standard deviations and relative recovery of Pb (II) was 4.9 % and 99.3 %, respectively (n=5).”
