摘要：
Intense emissions are produced in the u.v. and visible regions when arsine and stibine are introduced into a flow-type furnace-hydrogen diffusion flame system, when the flame is surrounded by oxygen. The emissions in the range 240-300 nm are attributed to AsO and SbO. The emission characteristics seem to be due to chemiluminescence based on the reaction between atomic analyte and oxygen. The detection limits are 0.05 μAs (10 ppb) at 429 nm and 0.1 μ Sb (20 ppb) at 369 nm. © 1979.
