Liquidliquid extraction

Liquidliquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Cyanide Removal From Coke Making and Blast Furnace Wastewaters

Initial two phase batch extraction tests using CCU as the amine solvent indicated an average 3.5/1 amine/ferrocyanide stoichiometry. Dispersion of the amine in ferrocyanide solution produced a finely dispersed wax. Subsequent addition of iron produced a floatable amine iron cyanide precipitate. Minimum iron addition was found to be 250 mg/l.
