- Abstract
Two wet acid digestion procedures using different heating techniques were tested on soil and plant certified reference materials for the determination of metals by inductively coupled plasma optical emission spectrometry (ICP-OES). The advantages and disadvantages of the two digestion methods were compared. The results obtained after conductive heating open vessel digestion were similar to those obtained by microwave assisted digestion both for soil and plant samples. The obtained recoveries (93-104%) showed that the procedures were precise and accurate for all elements, thus both digestion methods can be used for soil and plant sample dissolution prior to routine determination of metals by ICP-OES.
