METHOD OF EXTRACTING COLOR, RARE, RADIOACTIVE ELEMENTS

摘要

FIELD: separation. ^ SUBSTANCE: method comprises extracting elements from water solutions by organic solvent in the presence of a reagent from the set of derivatives of antipyrilmethane. The product of condensation of antipyrine with 2-methylpropanal is used as a reagent. The process is carried out at a temperature of 45-50°C with subsequent cooling of the products down to 10°C and formation of the melt of the extracting agent. The solvent is made of a mixture of bromoform and chloroform in a 1:10 ratio. ^ EFFECT: expanded functional capabilities. ^ 1 dwg, 1 ex
