FIELD: analytical chemistry. SUBSTANCE: for the purpose to obtain microquantities of diisopropyl ether of acid fluoride of methyl phosphonic acid preliminary stabilization of soil samples is necessary with 0.2n aqueous solution of hydrochloric acid. To obtain the highest quantity of the present substance it is necessary to apply ultrasound impact for 7-10 min. The present innovation provides the possibility to detect microquantities of substance in soil. EFFECT: higher efficiency. 5 tbl
