Thermal treatment of soil contaminated by transformation products of 1,1-Dimethylhydrazine
Main methods of soil treatment used in contamination by 1,1-dimethylhydrazine were considered in this paper. It was noted that during cleaning soils contaminated by propellants the content transformation products of 1,1-dimethylhydrazine is not considered, while they are not less dangerous pollutants. Thermal treatment of soil contaminated by main products of transformation of 1,1-dimethylhydrazine (1-methyl-1H-1,2,4-triazole, nitrosodimethylamine, dimetylaminoacetonitrile) was carried out. Calibration curves were constructed for the quantitative determination of these compounds. Efficiencies of thermal method of soil cleaning were showed. The optimal parameters of thermal treatment were established. The recommendations for developing a method of remediation of soil contaminated by transformation products of 1,1-dimethylhydrazine based on thermal treatment were made.
