Title Determination of acid vapours and mists at the workplace with the use of miniature absorbers
Original title Die Bestimmung von Säuredämpfen und Säurenebeln am Arbeitsplatz unter Verwendung von Kleinabsorbern [in German]
Bibliographic information June 1978, Vol.24, No.6, p.425-428. Illus.
Abstract Personal monitoring methods making use of miniature absorbers for determination of acid concentrations in workplace air are compared with regard to accuracy limits, suitability, and, in particular, degree of absorption. Use of an appropriate quantity of 0.01N NaOH (or KOH) as absorption fluid and back titration of the unused solution by means of automatic titration provides the most accurate results with a minimum of work.
