Extraction process

On the base of a stirred liquid-liquid extraction process, this column allowed

to extract the methylene blue solved in a saline aqueous solution by a polymer solution.

The polymer enrich in methylene blue can be regenerate by an adsorption process

who fixed the extract methylene blue.
