As an object of investigation are chosen the bottom system water - antipyrine - acetylsalicylic acid and aqueous mercury (II) solutions.
The aim of research was to study the mercury (II) distribution in the system water - antipyrine -acetylsalicylic acid. The researchers established the optimal ratio of antipyrine and acetylsalicylic acid within 1.0 mmol which is achieved by a quantitative Hg(II) extraction from model solutions. Under these conditions, the organic phase forms acetylsalicylate antipyrine, the aqueous phase have values pH = 2,70 and conductivity x = 121 mS/m. Maximum degree of extraction Hg(II) from model aqueous solution to the system water - antipyrine -acetylsalicylic acid was determined by atomic absorption spectrometry and total 984%.
Key words: bottom system, organic phase, mercury (II) extraction.
