METHOD OF ZINC EXTRACTION FROM BOTTOM SEDIMENTS WITH IONIC LIQUID Russian patent published in 2014 - IPC B01D11/02 G01N1/10 C02F1/26

Abstract RU 2523469 C1

FIELD: chemistry.

SUBSTANCE: method of zinc extraction from bottom sediments with an ionic liquid includes preparation of an analytic sample. Extraction of zinc from the solid sample is performed with application of the ionic liquid 1-butyl-3-methylimidazolium hexaphosphate with additives of ammonium thiocyanate and potassium iodide with further quantitative determination of zinc (II) ions in a concentrate of an organic phase of the ionic liquid.

EFFECT: providing degree of element extraction close to one hundred percent.
