Solvent extraction with trioctylphosphine oxide was used for the separation of rare earth elements (REE) and yttrium (Y) from geological samples decomposed by HF plus H2SO4 followed by alkaline fusion of the dry residue. The REE and Y were then measu

Although it is known that the use of long tubes in atomic absorption brings considerable increase in sensitivity, little is known about various factors affecting the sensitivity. In this work the role of fuel flow-rate for several elements (copper, s
