METHOD OF CONCENTRATING ORGANIC COMPOUNDS CONTAINED IN NATURALLY OCCURRING OBJECTS

摘要

FIELD: chemical analytical methods. SUBSTANCE: invention is aimed at developing method for concentrating organic compounds from aqueous solution simultaneously into two organic phases having no common interface. Aim is achieved by using three- phase extraction system prepared by mixing 2.7-3.0 M ammonium sulfate aqueous solution, 28-30% polyethylene glycol (PEG-1000) aqueous solution, and carbon tetrachloride. Method may find use in environmental analytical laboratories. EFFECT: improved procedure. 1 dwg
