OPTIMIZATION OF EXTRACTION PARAMETERS IN METAL OR AMMONIUM CHLORIDE - MONOALKYLPOLYETHYLENE GLYCOL - WATER SYSTEMS
The paper describes a systematic approach to the development of extraction systems based on nonionic surfactants. It consists in selection of salting-out agent on basis of its salting-out ability estimate toward to studied surfactant and temperature and concentration parameters of process optimization by constructing polythermal phase diagrams of salting-out agent - surfactan - water systems. Algorithm realization made it possible to propose NaCl - Synthanol DS-10 (Synthanol ALM-10) - water systems, which are promising for micellar extraction at 60 °C. Preliminary tests have shown the possibility of concentrating a number of organic complexing reagents of different nature.
