CYANOGEN CHLORIDE DETECTION MATERIAL

PROBLEM TO BE SOLVED: To provide an easily-handleable cyanogen chloride detection material suitable for monitoring, with a background that cyanogen chloride is a poisonous substance wherein the acceptable concentration (TLV) of a chemical substance in the air in a working environment is regulated at 0.3 ppm and its concentration is strictly regulated. SOLUTION: This cyanogen chloride detection material is formed by impregnating a reagent generating a color reaction reacting with cyanogen chloride into a permeable carrier including a gas adsorbent. Since the detection material generates a color change corresponding to the concentration of cyanogen chloride reacting with cyanogen chloride only be being left as it is in an environment, the concentration can be monitored without requiring a work of sample collection or the like. In addition, since a moisture absorbent such as glycerin is not included, a reaction of the reagent with miscellaneous gases in the environment or cellulose when the carrier is constituted of the cellulose can be prevented to the utmost, and long-time preservation is possible without changing detection sensitivity.
