Sodium hydroxide solutions, percent

Dissolve 5 g chloramine T in 100 ml 0.5 percent sodium hydroxide solution [1]. 

Note In the second spray potassium hydroxide solution can be replaced by sodium hydroxide solution or by a solution of 17 g benzyltrimethylammonium hydroxide in 100 ml 33 percent methanol [4]. The Kedde reagent [13] can also be applied very sue-... 

RECOMMENDED FIELD PROCEDURES Spills must be contained by covering with vermiculite, diatomaceous earth clay, fine sand, sponges, and paper or cloth towels. Decontaminate with copious amounts of aqueous Sodium Hydroxide solution (a minimum 10 wt percent). Scoop up all material and place in a fully removable head drum with a high density polyethylene liner. Cover the contents of the drum with decontaminating solution as above before affixing the drum head. 

If 10 wt. percent aqueous Sodium Hydroxide solution is not available then the following decontaminants may be used instead and are listed in the order of preference Decontamination Solution No. 2 (DS2), Sodium Carbonate, and Supertropical Bleach Slurry (STB). 

An alternate solution for the decontamination of GD is 10 percent Sodium Carbonate in place of the 10 percent Sodium Hydroxide solution above. Continue with 55 grams of decon per gram of GD. Agitate for one hour and allow to react for 3 hours. At the end of the third hour adjust the pH to above 10. It is also permitted to substitute 5.25% Sodium...

In the process, miscella leaves the extractor at about 30-35 percent oil and is concentrated to approximately 65 percent oil by evaporation. The FFA in the concentrate then is reacted with alkali (sodium hydroxide solution) to produce soaps that are removed with other water-soluble compounds by centrifugation. Next, the solvent is removed from the miscella-refined oil by further evaporation, and the soapstock is spread on the meal in the DT to recover its solvent. Hexane vapors from the miscella and the DT are condensed, and the solvent is recycled to the extractor for reuse. The noncondensable gases are passed through a mineral oil stripper to recover the last traces of hexane. 

Small Areas Ventilation. In heavily contaminated areas, decontamination with copious amounts of aqueous sodium hydroxide solution (a nunimum of 10 percent by weight) may be required. If sodium hydroxide solution is not available, then sodium carbonate may be used. Removal of porous material, including painted surfaces, that may have absorbed Nerve Agent vapor may be required as these materials could continue to re-release vapor after exposure has ceased. 

Small Areas Consolidate as much material as possible and place into containers. In heavily contaminated areas, employ vacuum devices equipped with High Efficiency Particulate Air (HEPA) filters to remove as much agent as possible. Decontaminate the area with a fresh solution of HTH pool bleach in denatured alcohol (approximately 9 percent by weight) followed by decontamination with copious amounts of aqueous sodium hydroxide solution (a minimum of 10 percent by weight). Vigorous off-gassing may occur during this process.
