| description | The applicability of existing methods of extraction and chromatographic determination of mobile forms of 1,1-dimetylhydrazine and an important product of its oxidation transformation—N-nitrosodimethylamine—for analysis of peaty boggy soils typical for the European North of the Russian Federation is evaluated. It is shown that within a 3-day period after 1,1-dimetylhydrazine penetration into the soil, no more than 15% of its initial content may be extracted. It is revealed that the greatest amount of unsymmetrical dimethylhydrazine is extracted from peat upon distillation with steam in the medium of 40% solution of sodium hydroxide. Conditions of sample preparation and chromatographic determination of nitrosodimethylamine in soils with high organic matter content are optimized. |
