| Abstract |
|
Major and trace toxic elements in commercially available actinolitums were analyzed. The known chemical formula were Ca2(Mg · Fe)_5(Si_4O_11)_2(OH)_2 and the major elements of Ca, Mg, Fe and Si were measured by ICP/OES and XRF simultaneously and the results were compared to evaluate the accuracy. ICP/OES provides quite low concentration data compare to the XRF data due to the solubility problem during the pre-treatment process. Trace toxic elements such as As, Cd, Pb and Hg were analyzed by ICP/OES and mercury analyzer.
According to XRF data, all the collected sample was turn out to be standard materials except Ac21. Most of toxic heavy metals were almost negligible except Hg contents in Ac8, Ac18 and AcP1. |
