| Abstract |
Occurrence, uses, toxicity and first aid information are given for arsenic and its inorganic compounds. Determination method: Arsenic trioxide (in its vapour form) is collected on a paper filter treated with a sodium hydroxide solution; particulate arsenic dust and fume are collected together with arsenic trioxide or separately on a mixed cellulose ester filter; the filters are then treated with aqua regia to oxidise and dissolve the arsenic compounds; the resulting solution is analysed by atomic absorption spectrometry using the hydride evolution technique either directly or combined with the method of standard additions. Scope: suitable for sampling over periods of 10min-8h. Lower analytical limit: 0.005mg As/m3 for samples of 20L of air. Precision:<10%. The presence of many metals will cause interference, which can be eliminated by using the method of standard additions. |
