Full textThe development of new processes for the recovery of palladium from recycling materials like spent automotive catalysts is of economic and ecologic interest. In this thesis new solvent and solid phase extractants have been designed, which are suitable for the recovery of palladium(II) from an oxidising hydrochloric leach liquor that does not only additionally contain platinum and rhodium but also a number of base metals. In contrast to many extractants described in the literature these new extractants – unsaturated monomeric dithioethers as well as oligomeric mixtures of ligands with vicinal dithioether units – are highly selective for palladium(II). Due to their geometric and electronic preorganisation they form stable square-planar chelate complexes with palladium(II). For the development of the solvent extractant a series of unsaturated dithioethers, which are based on a rigid 1,2-dithioethene unit that is imbedded in an electron-withdrawing backbone, with polar end-groups has been synthesised. In addition to the determination of the crystal structures of the ligands and their dichloridopalladium complexes, the electro- and photochemical properties, the complex stabilities and the behaviour in solution have been investigated. Solvent extraction experiments showed the superiority of some of our ligands over conventionally used extractants in terms of their very fast reaction rates. Considering criteria that are essential for industrial utilisation like: robustness towards oxidation, achieving of high extraction yields (even at a high hydrochloric acid content of the leach liquor), fast extraction kinetics and a high selectivity for palladium(II), 1,2-bis(2-methoxyethylthio)benzene was selected as the extractant of choice. Building on this a solvent extraction system close to industrial practice was devised. After stepwise adaption of the aqueous phase from a model solution to the oxidising hydrochloric leach liquor, the selection of a diluent suitable for commercial operations (1,2-dichlorobenzene) and of an efficient stripping agent (0.5 M thiourea in 0.1 M HCl) has been accomplished. The high selectivity of that solvent extraction system for palladium(II) could be verified and its reusability and suitability for practical application have been proven. Further it was shown that small amounts of the thioether sulfoxide 1-[(2-methoxyethyl)sulfanyl]-2-[(2-methoxyethyl)sulfinyl]benzene form when the dithioether ligand 1,2-bis(2-methoxyethylthio)benzene gets in contact with oxidising media. Under acidic conditions this thioether sulfoxide gets protonated and accelerates the extraction like a phase transfer catalyst; without decreasing the selectivity for palladium(II). The molecular structure of the corresponding dichloridopalladium complex reveals that the nonprotonated ligand coordinates palladium(II) in a similar manner to the dithioether via the chelating sulfur atoms. Mixtures of oligo(dithioether) ligands and the monomeric 1,2-bis(2-methoxyethylthio)benzene have been adsorbed on silica gel and amberlite® XAD 2. These SIRs (solvent impregnated resins) have been used for solid phase extraction experiments. The oligo(dithioether) ligands are based on 1,2- dithiobenzene or 1,2-dithiomaleonitrile units, which are connected via tris(oxyethylene)ethylene or trimethylene chains. With the help of batch experiments it could be shown how structural differences, like the chelating unit, the kind of linking chain and the type of supporting material, impact the extraction yield, kinetics and loading capacity. The SIRs containing silica gel establish the extraction equilibrium much faster than those containing amberlite® XAD 2. On the other hand, the extractants permanently remain on amberlite® XAD 2, in contrast to silica gel. In a hydrochloric medium 1,2-dithiobenzene derivatives are better extractants than 1,2-dithiomaleonitrile derivatives. In column experiments with the oxidising hydrochloric leach liquor and reusable SIRs based on 1,2-dithiobenzene derivatives impregnated into amberlite® XAD 2, it appeared that for the implementation of high loading capacities very low flow rates are required. The selectivity for palladium(II) of these solid phase extractants could be demonstrated, although the eluates, in contrast to the eluates gained from the solvent extraction experiments, contained not only palladium but also small amounts of platinum, aluminium, iron and lead.
