FIELD: chemistry.
SUBSTANCE: method of mercury (II) extraction from chloride solutions includes extraction of mercury from a water phase into an organic component of a stratifying system water-antipyrine-organic acid. To provide quantitative concentration of mercury (II) in a hydrophobic melt of an organic phase of antipyrinum acetylsalicylate antipyrine and acetylsalicylic acid in a molar ratio 1:1 are used. In the course of the process heating on the water bath to a temperature of 90°C for 20-30 minutes, intensive shaking up and mixing are carried out. Sediment of the organic phase represents a mercury concentrate and can be used as an analytic sample.
EFFECT: invention makes it possible to reduce antipyrinum consumption.
