English Abstract Optimum 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.
