Abstract niet beschikbaarOptimum conditions with respect to power, time and type of acid were established for the digestion of soil samples in a microwave furnace for the ICP-AES determination of trace metals. For the ICP-AES determination a selection for the proper spectral lines was made with respect to spectral interferences both "on the line" and at the position for the background measurement. The extent of matrix induced sensitivity changes was determined. The procedures were tested by digesting and analysing soil samples with known concentrations of trace metals.RIV
