EXPRESS DETECTION OF CHEMICAL SUBSTANCES ON THE SURFACE OF EQUIPMENT OF CHEMICALLY HAZARDOUS OBJECTS
Abstract
Analytical systems suitable for creating a tool set for rapid colorimetric detection of surface contamination of the equipment of chemically hazardous production facilities with hydrazine (its derivatives), nitric acid, and nitrogen oxides, are considered and evaluated. An indication system for rapid detection of hydrazine and its derivatives is based on aqueous solutions of cobalt(II) chloride, nitrate or sulfate, while elements for indication system for rapid detection of nitric acid and nitrogen oxides are acidified aqueous solutions of potassium iodide with starch addition. A technical solution for implementation of express detection tool kit in the form of reusable aerosol packaging is proposed. The main advantages of the kit are high sensitivity and specificity for detectable substances, short detection time (not exceeding 2 minutes), duration of indication effect (at least 5 minutes), ease of use (no special qualification is required), etc. The tool kit can be applied for determining the presence of micro leakages in technical equipment parts and equipment surface residual contamination with the hazardous chemical compounds.
