Abstract

A vortex-assisted liquid-phase microextraction was applied for the extraction of trace amounts of platinum(II) prior to flame atomic absorption spectrometry detection in the water sample. Ammonium pyrolysine dithiocarbamate was used as the chelating agent and n-octanol as an extractant. The fine droplets of n-octanol were made and dispersed as a cloud in the aqueous sample with the help of vortex mixing. Different parameters such as the pH, the amount of ammonium pyrolysine dithiocarbamate, the composition and volume of the extraction agent and vortex time were studied to get the optimum results. Under optimal conditions, the low limit of detection is 2.0 μg mL^-1. Recoveries of platinum spiked into tap water samples were in the range of 85.0~91.5 %. The relative standard deviations is 2.12 % (n = 6). The correlation coefficient of the calibration curve is 0.9977. The proposed method was successfully applied for the determination of platinum in the real tap water samples.
