Development of an analytical method for the determination of platinum in urban dust in the agglomeration of Brno, Czech Republic
Original language description
This thesis studied conditions for preconcentration and determination of platinum in airborne dust. Octadecyl modified silica gel was tested for solid phase extraction for preconcentration of platinum. The ion associates made from platinum chlorocomplexes with cationic surfactant Septonex (carbaetoxypentadecyl trimethylammonium bromide) were sorbed on modified silica gel in the presence of 0.1 mol.l-1 HCl. The retained amount of platinum was eluted with acetonitrile. Recovery values of platinum from model solution were above 90 %. Platinum in eluate was determined by atomic absorption spectrometry with electrothermal atomization (ET-AAS). Samples of airborne dust particulates from filters were decomposed in aqua regia by microwave extraction. This work published yearly monitoring of platinum content in airborne particulate matter in Brno agglomeration, which was determined for each month. Platinum concentration was obtained in interval 2.3–51.5 pg.m-3 in air, which corresponds to 61.9 – 2997.7 ng.g-1 in airborne dust.
