METHOD FOR DETERMINATION OF UNSYMMETRICAL DIMETHYLHYDRAZINE, HYDRAZINE AND NITRITE ION IN WATER

摘要

FIELD: analysis of rocket fuel components. SUBSTANCE: analyzed sample is decolorized. The process takes place with the help of calcium oxide, their mass ratio being 1:0.05-0.15. Then 66-70 % solution of orthophosphoric acid is added, mass ratio of calcium oxide and fluorophosphoric acid being 1:0.2-0.4. Thus obtained decolorized solution is separated, coloring reagent is added into and colometric analysis is carried out. EFFECT: improved efficiency of the method. 2 tbl
