METHOD FOR DEFINITION OF CONCENTRATION OF TRINITROTOLUENE AND AMMONIUM NITRATE IN AQUEOUS SOLUTIONS FORMED AFTER EXTRACTION OF AMOTOL FROM AMMUNITIONS BEING UTILIZED

摘要

The utility model relates to analytical chemistry. A method for definition of concentration of trinitrotoluene and ammonium nitrate in aqueous solutions formed after extraction of amatol from ammunitions being utilized comprises direct areomectric definition of ammonium nitrate density and photocolorimetry of colored solution of trinitrotoluene adduct with sodium sulfite. For the definition of ammonium nitrate solution and concentration of trinitrotoluene the explosive is preliminarily extracted from the solution of ammonium nitrate by a method of extraction, and the extraction is carried out by chloroform. After separation of extragent trinitrotoluene is dissolved in ethyl alcohol with subsequent dilution of extract with water for photocolorimetry of alcoholic and aqueous solution.
