Extra information

After removing the major part of the matrix elements and other accompanying ions from the digested plants by an extraction with acetylacetone/methylisobutyl-ketone in presence of EDTA, subsequently followed by a reextraction with nitric acid, this element can be determined interference-free by means of flameless atomic absorption with non-coated and zirconium-coated graphite tubes as electrothermal atomizers. During the above mentioned extraction-reextraction procedure only very small amounts of aluminium and iron are coextracted and did not interfere with the determination of beryllium. Recovery analyses confirmed that the whole analytical procedure was quantitative. The detection limit of beryllium was found to be 1.5 μg/l reextract. As an example, roots, stems and leaves of "Calluna vulgaris" were analyzed.
