Cantech (stream sediment) AAS (Bi, Se; flameless)
Cantech, stream sediment; AAS (Bismuth, Selenium; flameless)
A 1000 mg portion of prepared sample was digested in an acid mixture (3:1 nitric: hydrochloric acids) in a water bath at 90° C for 2 hours. After cooling, adjusting the final volume and allowing the solids to settle, an aliquot of solution was removed and analysed for bismuth and selenium by flameless atomic absorption spectrometry using sodium hydride as reductant. The hydrides were passed through a heated quartz cell where the absorption was measured.
