Abstract

A method to quantitatively measure stibine (SbH/sub 3/) in air is reported. The stibine is removed from the air and trapped in a pyridine-silver diethyldithiocarbamate solution and the antimony content of the solution determined by flameless atomic absorption spectrometry. The sensitivity of the method is suitable for the measurement of stibine concentrations well below the threshold limiting value of 0.5 mg of stibine/m/sup 3/ air recommened by the American Conference of Government Industrial Hygienists. 3 tables, 1 figure.
