Bestimmung von As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, V und Zn in Kohlen, Additiven, Flugaschen und Impaktorfilterst?uben aus Kohlekraftwerken

Summary The analysis of coal, additives and combustion residues of coal-fired power plants is described. The selection of the best decomposition method has a special meaning for the type of sample (coal, additive etc.) as also for the elements to be determined in the different samples. There is no universal method which fits all the different samples and no universal determination system for this problem. Problems of the determination of chromium and arsenic are described and discussed due to the matrix and the decomposition technique. The determination with another independent method and the measurement of certified reference material is a good approach to the true value of the elements to be determined in the samples.
