Application of microwave-assistet decomposition procedures in analysis of dust aerosols

Abstract

The use of microwave-assisted digestion in analyses of airb orne particulate matter. The analytical procedure of sample preparation for AAS measurements of selected analytes (As, Cd, Cr, Mn, Ni, Pb, Zn) was developed. The validation of a method was done by analyses of SRM 1648 (NIST) and by using a new testing material - urban dust. The preparation of this material was described. Recommended values of selected analytes given by different independent methods (AAS, ICP-OES, ICP, MS, INAA and PIXE) are included
