The emission spectroscopy of some elements in high-temperature flames
The emission of atoms of a large number of elements in laminar high-temperature acetylene-N 2 O, H 2 -N 2 O, H 2 -O 2 , acetylene-air, and H 2 -air flames was studied; of these the most suitable are flame mixtures containing N 2 O. Methods were developed for determining Ca, Sr, Ba, for Cu, Cr, Mn an...

O flame. A small chemical interference for the matrix elements was found provided that a monochromator with good resolution and with a small amount of scattered light was employed. These conditions are fulfilled by most modern atomic absorption instruments with which comparable results are obtained. |
