Chlorine gas decontaminant

Abstract

The invention discloses a chlorine decontaminant, which is characterized in that the chlorine decontaminant is prepared by mixing organic reducer accounting for 89.8 percent to 96 percent of the total weight, 3 percent to 10 percent of surfactant, 0.1 percent to 0.5 percent of thickener polyvinyl alcohol (PVA) and 0.1 percent to 0.5 percent of foam stabilizer dodecyl dimethyl amine oxide (DDAO). The organic reducer is chosen from soluble oxalate, citrate or ascorbic acid, starch, glucose, fruit sugar, tartrate, malate or lactate; the surfactant is chosen from polyoxyethylene alkyl ether sulfo-sodium succinate, coco-amide propyl betaine (CAPB), alpha-alkenyl sulfonate sodium, fluorine surfactant or sodium ethoxylated alkyl sulfate. When the decontaminant is carried out, the water solution with the concentration being 0.3 percent to 10 percent (weight percentage) is used and sprayed to the leakage area of chlorine by a fine water atomizing nozzle; the decontaminant of the invention combines physical dilution and chemical reaction, thus inhibiting the diffusion of chlorine and enhancing the reaction ratio, and the remained substances of the reaction are free of contamination and can be easily decomposed.

Description

technical field [0001] The invention belongs to the technical field of chlorine gas decontamination agents, in particular to a chlorine gas decontamination agent containing an organic reducing agent and a surfactant and a preparation method thereof. Background technique [0002] At present, the main treatment methods for chlorine gas leakage include chemical decontamination and physical decontamination. [0003] Existing chemical decontamination methods usually use a large amount of water or add sodium hydroxide, calcium hydroxide or sodium carbonate, sodium bicarbonate to absorb and neutralize chlorine gas. For example, Chinese Patent Publication No. CN1066991A proposes a method for decontaminating chlorine gas leaks, which uses reducing inorganic salts such as sodium thiosulfate, potassium iodide or ammonia water to be dissolved in water and sprayed on the poisoned area or the surface of the contaminated material for reaction absorption; and In the 2006 National Caustic S...

AI Technical Summary

Problems solved by technology

The physical decontamination method cannot essentially eliminate the impact of chlorine gas on the environment, and if the adsorbent is used, the adsorbed product must be treated, adding treatment steps, and the treatment method has yet to be considered

[0011] The above-mentioned existing traditional methods are difficult to achieve true harmless disposal under a large amount of chlorine gas leakage and harsh environmental conditions, and often cause the harm of chlorine gas to be transferred
