• Methods for analyzing low concentrations of chlorine in air are discussed. The use of 0.2% sulfamic acid solution for the collection of chlorine made it possible to sample air in large quantities as much as 2.0 l/min for 60 min. Sulfur dioxide and ammonia, which are interfering gases could be completely removed by the use of a chromic acid scrubber. The color that developed was stable for more than 60 min when the barbituric acid method of Asmus, et al. was employed. Quantitative determination was carried out fluorospectrometrically with a detection limit of 0.03 to 0.04 ppb. A good analytical precision was obtained with a coefficient variation of 5.3% for 6.6×10^<-6> mol of Cl_2.
