SIMULATOR OF CHEMICAL CONTAMINATION OF SOIL WITH O-ISOBUTYL-S-2(N,N-DIETHYLAMINO)ETHYLMETHYLPHOSPHONATE

摘要

FIELD: chemistry.;SUBSTANCE: disclosed is use of nontoxic and readily available aqueous solution of picric acid (2,4,6-trinitrophenol) as an O-isobutyl-S-2-(N,N-diethylamino)ethylmethylphosphonate imitator, with the following ratio of components, wt %: picric acid 0.8-1.1; water 98.9-99.2.;EFFECT: aqueous solution of picric acid has physical and chemical properties in soil similar to those of toxic organophosphorus toxic substance, which enables to investigate propagation thereof in soil.;1 tbl
