Crowned dithiomaleonitrile are macrocyclic chelate ligands which extract Pd(II) at sufficient rate in a very good yields. The synthesis of the immobilised ligands proceeds from the 2-allyloxy-1,2-propanediol forming the dicar-bon acid which is reduced to the diole. With the help of thionylchloride the dichloro compound is synthe-sized forming the macrocycle together with a dithiolate (1,2-disodium-1,2-dicyanethene-1,2-dithiolate, 1,2-disodium-4-methylbenzene-1,2-dithiolate) at high dilution conditions. The allylsubstituted crown ether is sillylated and the resulting alkoxysilane is immobilised onto activated silica gel. The extraction results with crown ethers are compared with that achieved with the help of substituted ß- diketones and 4-acyl-5-pyrazolones. By modification of the cavity of the macrocyclus the extraction rate increases from the acyclic compound through maleonitrile-dithio-21-crown-7, maleonitrile-dithio-15-crown-5 and maleonitrile-18-crown-6. The best results can be observed at the maleonitrile-dithio-12-crown-4. The rise of the function log D= f(log L) gives the composition of the extracted compounds as 1:1. The separa-tion is unsatisfactory in the case of Ag(I), Hg(II), Pt(II), Tl (I) and the most 3d-elements. Summarizing, a very good separation of palladium from the examined elements can be specified. Additional to the extraction experiments, as well as the crystal structures and by UV spectroscopy the for- mation constants of selected chelates were determined.}, language = {en} } @article{GrunewaldBukowskySchade1996, author = {Grunewald, Karsten and Bukowsky, Heinz and Schade, Werner}, title = {Schwermetalle und deren Bindung in B{\"o}den und Substraten des Rieselfeldgebietes s{\"u}dlich Berlin}, year = {1996}, language = {de} } @article{BurhenneBukowskySchneider1997, author = {Burhenne, Matthias and Bukowsky, Heinz and Schneider, Ingo}, title = {Schwermetalle in B{\"o}den der Rieselfelder Berlin-S{\"u}d}, year = {1997}, language = {de} } @article{GrunewaldBlumensteinBukowskyetal.1995, author = {Grunewald, Karsten and Blumenstein, Oswald and Bukowsky, Heinz and Schade, Werner}, title = {Schadstoffe in Vorflutsedimenten des Rieselfeldgebietes s{\"u}dlich von Berlin}, year = {1995}, language = {de} }
