摘要：

Sampling methods for the determination of volatile inorganic compounds in workroom air are described. The main factor affecting the adsorption capacity of activated charcoal for iron pentacarbonyl is air flow rate. Nickel tetracarbonyl is collected quantitatively at flow rates of up to 1 1/min if the volume of air sampled does not exceed 1001. Arsine, phosphine and stibine are collected quantitatively from air by use of a double filter air cassette Silver nitrate impregnated backing pads are shown to trap the hydrides with better than 99.9% efficiency. Several atomic spectroscopic methods have been applied to the determination of these volatile species, with electrothermal atomic absorption and inductively coupled plasma atomic emission spectroscopy being preferred. Concentrations of the hydrides in various workroom atmospheres were found to be well below the Threshold Limit Values.
