Título: The Spectroscopic determination of coal tar pitch volatiles / E.K. Harrison and B.S. ThomasAutor: Harrison, E.K.
Notas: Sumario: A spectrometric method has been developed for the determination of coal tar pitch volatiles in extracts of particulate matter collected from the atmosphere at coking works. After calibration against extracts of known concentration, it enables determinations to be made with an accuracy comparable to that of the gravimetric method presently in use, namely 2.6 microg. ml-1 extract. The method has the advantage that the result can be obtained in a fraction of the time required by the gravimetric methodRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 3, 1987 ; p. 357-361Materia / lugar / evento: Higiene industrial Contaminantes químicos Carbón Benceno Alquitranes Espectroscopia Métodos de análisis Otros autores: Thomas, B.S.
