FIELD: chemistry.
SUBSTANCE: mercury concentrating from liquid samples according to the invention is carried out by means of the aqueous delaminating system containing derivant of pyrazyl ketone and organic acid. Delaminating in system is carried out due to chemical interaction of "pharmaceutical" antipyrine and salicyl-sulphonic acid with unique dissolvent - water. At delaminating the bottom phase of ionic organic liquid is formed, which put in microliter quantities on a graphitized electrode surface. Then it is put in a three-electrode mesh with HCl about 0.1 mole/l, it is submitted voltage potential of mercury accumulation - 1.4 W within 30 seconds and then in a mode of anodic scan voltamperegram is displayed with peak of the mercury anodic oxidation, observed at potential within 0.00-0.10 W and linearly depending on mercury concentration in an ionic liquid, in a mode of direct current at a scanning speed of 80 mW/sec over the range from -1.2 to 1.0 W.
EFFECT: reduction in price of the analysis procedure.
