Extraction of rhenium (VII) by tetraoctylammonium bromide mixed with low-melting thinners

Extraction of rhenium (VII) by tetraoctylammonium bromide mixed with low-melting thinners

Regularities of extraction of rhenium (VII) melt tetraoctyl-ammonium bromide in a mixture of higher alcohols and paraffin were determined. Quantitative extraction of measurements obtained in the range of pH of the aqueous phase 1.5–2.0 was carried out. It was shown that the degree of extraction of r...
