Abstracts
A passive chemical dosimeter for the determination of a long exposure of N-substituted aromatic amines in air is described. The analytes are accumulated on a sorption filter by the many-hour exposure of a unit using a chemical reaction with a selective reagent. The diffusion coefficients, rate of chemisorption preconcentration, and detection limits of chemical dosimeters are found. The concentrations of N-methyl-aniline, N,N-dimethylaniline, and diphenylamine in air samples are determined.
