Solvent extraction and separation of lanthanoids with mixtures of chelating extractant and 4-(2-pyridylazo)-resorcin
The solvent extraction of trivalent lanthanoids (La, Nd, Eu, Ho, and Lu) with mixtures of the chelating extractant 1-(2-thienyl)-4,4,4-trifluoro-1,3-butanedione (thenoyltrifluoro-acetone, HTTA) or 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-on (HP) and 4-(2-pyridylazo)-resorcin (PAR, S) in CHCl3 was studied. It was found that in the presence of 4-(2-pyridylazo)-resorcin the lanthanoids were extra...
متن کاملCoordination and extraction of mercury(II) with an ionic liquid-based thione extractant.
A neutral thione extractant, 1,3-diethylimidazole-2-thione (C2C2ImT), was prepared from an ionic liquid (IL), 1,3-diethylimidazolium acetate, and used within a hydrophobic ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethane)sulfonamide ([C2mim][NTf2]), to extract Hg(II) from aqueous solutions of HgCl2 or Hg(OAc)2. Investigations of the extraction mechanism, spectroscopic analyses of ...
متن کاملExtraction and Separation of Fucoidan from Laminaria japonica with Chitosan as Extractant
Herein the extraction method of fucoidan from Laminaria japonica is reported. Firstly, chitosan, chitosan-N-2-hydroxypropyl trimethyl ammonium chloride (HACC), and hexadecyltrimethylammonium bromide (CPAB) were used to extract the fucoidan. The results showed that chitosan was the optimal extractant compared with the other two extractants. After extraction, different aqueous solutions, includin...
