PROCESS OF DETECTION OF ASYMMETRIC DIMETHYLHYDRAZINE IN SOIL Russian patent published in 1998 - IPC

Abstract RU 2114428 C1

FIELD: analytical control of environment for content of components of rocket fuels having toxic properties. SUBSTANCE: sample of soil is treated with calcium oxide with mass proportion 1.0:0.5-1.5. Then water is added with subsequent heating to 90-97 C in the course of 7-15 min. After this it is treated with aqueous solution of orthophosphorus acid, obtained solution is filtered, filtrate is treated with color reagent. Finally solution is subjected to photometric analysis. EFFECT: improved authenticity and efficiency of process. 2 tbl
