Separation of Flavonids by Means of Solvent Extraction.

Recovery of benzaldehyde from aqueous streams using extractant impregnated resins

“…Already a lot of research has been done in this field for removal of traces of metals from aqueous streams [2][3][4]. Lately, the EIR technology has been extended for recovery of organic compounds, like phenols [5], flavonoids [6], carboxylic acids [7][8][9][10], amino acids [11,12], and antibiotics (spiramycin [13]). In the present research, we investigate the removal of aldehydes from diluted aqueous streams using EIR technology, which has, Nomenclature Symbols n amount of substance, mol C concentration, mol/l K r reaction equilibrium constant, l/mol K ph physical partitioning ratio D overall distribution ratio, defined by Eq.…”
