摘要：

A method for the determination of chloroacetyl chloride (CAC) in air is described. CAC is sampled with commercially available silica gel collection tubes, desorbed with sodium bicarbonate solution, and determined by ion chromatography. A dynamic standard generator for CAC was developed and used to validate the method in the range of 3.7-76.7 μg CAC. Average recovery was greater than 99% for both mono-chloroacetate and chloride. The relative standard deviation was 0.072 for monochloroacetate and 0.088 for chloride. The reliable quantitation limit for CAC is ca. 0.01 ppm but can be improved readily if desired. © 1979, American Chemical Society. All rights reserved.
