Popis: | Tetradentate and octadentate sulfur containing macrocyclic polythiaethers 1,4,8,11-tetrathiacyclotetradecane (TTP) and 1,4,8,11,15,18,22,25-octathiacyclooctacosane (OTO) have been used for mercury(II) extraction from chloride and perchlorate solutions. HgCl2L and ionic HgL2+ complexes form in the organic phase (L = TTP or OTO respectively). The equilibrium constants which characterize the extraction were calculated. The complexes Hg(TTP)Cl2, Hg2(TTP)Cl4·4 H2O, [Hg(TTP)](ClO4)2·2 H2O, [Hg(OTO)](ClO4)2·2 H2O and Hg4(OTO)Cl8·4 H2O have been prepared and characterized. IR and Raman spectra have been recorded, the characteristic frequencies of the vibrations ClHgCl, SHgS and CSC have been assigned. |
