Hierarchische Selbstorganisation von Helicaten mit substituierten 8-Hydroxychinolinliganden
… was the synthesis of complexes with different divalent metals, starting from alkyl 8-hydroxyquinoline-7-carboxylate and 1-alkyl-3-(8-hydroxyquinolin-7-yl)urea and investigations of the monomer-dimer-equilibrium. Hydrophilic and hydrophobic ligands had been done and used successfully for …

The kinetics of liquid-liquid extraction of metals in a rotating diffusion cell. A rotating diffusion cell is used to study the rates of extraction of divalent transition metals by di-(2-ethylhexyl)-phosphoric acid and a sulphur analogue. A chemical-diffusion model describes the rate curves.
… used to study the kinetics of extraction of the transition metals cobalt (II), nickel (II), copper (II) and zinc (II) from sulphate solutions into either of two extractants held in n-heptane; di-(2-ethylhexyl) phosphoric acid (D2EHPA) or di-(2- ethylhexyl) dithiophosphoric acid (D2EHDTPA). The …
