Publikováno v: Supramolecular Chemistry. 22:347-357

Calix[4]arene derivatives fixed in the 1,3-alternate conformation and substituted at one side by four carbamoylmethylphosphine oxide (CMPO) residues were synthesised. Two CMPO groups are directly attached to the wide rim, while the second pair is bou

Recognition of Some Lanthanides, Actinides, and Transition- and Heavy-Metal Cations by N-Donor Ligands: Thermodynamic and Kinetic Aspects

Autor: Véronique Hubscher-Bruder, Saliha Bouhroum, Jaouad Haddaoui, Françoise Arnaud-Neu

Publikováno v: Inorganic Chemistry. 49:1363-1371

The remarkable actinide(III) selectivity of the polyaromatic N-donors bis-triazine-pyridines (BTPs), hemi-bis-triazine-pyridines (hemi-BTPs) and bis-triazine-bipyridines (BTBPs) make these ligands the most promising candidates in partitioning and tra

Non‐dispersive Solvent Extraction of Alkali Metals with the Dicyclohexano 18 Crown 6: Evaluation of Mass Transfer Coefficients

Autor: Michel Burgard, Dominique Trébouet, Jaouad Haddaoui, José M. Loureiro

Publikováno v: Separation Science and Technology. 39:3839-3858

The aim of this study is both to check the feasibility of the membrane contactor for the extraction of alkali metals with the dicyclohexano 18 crown 6 as extractant and to obtain informations about the mass transfer of these metals. The influence of

Publikováno v: Talanta. 74(1)

The binding of lanthanide(III) cations with organophosphorous ligands like CMPO and related calix[4]arene-based derivatives have been investigated using two experimental methods. The stability constants of the lanthanum, europium and ytterbium comple
