摘要: Hydride generation (HG) coupled to a simultaneous multi-element axially viewed inductively plasma atomic emission spectrometer (ICP-CCD-AES) was used determine trace contaminants (<10 mg kg−1) of As, Bi, Se, Sn, and Te in chemically resistant high alloy steels Ni alloys. These refractory samples were quantitatively digested using mixed acid microwave-assisted procedure. EDTA, tartaric 2-pyridinecarbaldehyde oxime evaluated as interference-retarding agents. Accuracy spiked synthetic steel solutions CRM Limits quantification (LOQs) calculated for the solid material varied from about 1–10 kg−1 satisfactory data obtained Sn Te. However, LOQs Sb degraded and, result, this LOQ could not be determined with accuracy tested.
