Abstract

A microwave assisted vapour-phase digestion procedure was developed for microanalytical investigation of airborne dust samples collected on cellulose nitrate filters. Decomposition of the filter placed into a quartz microvial was carried out by oxidation using a mixture of HNO3+H2O2 in a closed Teflon bomb. To avoid the charring of the filter the temperature was increased from 25 °C to 180 °C in 5 steps during 97 minutes. The decomposition rate of cellulose nitrate amounted to 95%. The recovery of Ni, V, Pb, Pt and Pd ranged from 85% to 94%. The applicability of this sample preparation procedure resulting in 1 cm3 solution was demonstrated by investigation of airborne dust samples collected in the Clark tunnel in Budapest applying total reflection X-ray fluorescence (TXRF) spectrometiy.
