METHOD FOR EXTRACTION OF MERCURY AND SELENIUM INORGANIC FORMS FROM SOLID SAMPLES OF NATURAL OBJECTS Russian patent published in 2009 - IPC C01B19/00 C01G13/00 B01D11/02 

FIELD: chemistry.

SUBSTANCE: method for extraction of the mercury and selenium inorganic forms from the solid samples of natural objects includes mercury and selenium extraction from the solid phase of the natural objects to the organic phase of the settling system "water-antipyrin-sulfosalicylic acid". The latter was prepared by the mixing of antipyrin and sulfosalicylic acid 2M solutions in volume ratio 2:1.

EFFECT: decreasing of environment contamination during preparation of the solid samples of natural objects.
