    • Pilot-scale tests were conducted at MEFOS for the production of zinc oxide from Electric Arc Furnace (EAF) dust using a DC arc furnace with a hollow electrode suitable for the processing of fine-grained materials. The association of halides in Electric Arc Furnace (EAF) dust and zinc oxide fume before and after water leaching was investigated by XRD, SEM, and TEM analysis. In EAF dust, chlorine and fluorine were found to exist primarily as NaCl, KCl, and CaF2. After water leaching of the zinc oxide fume the halide concentrations were reduced to about 200 ppm Cl and 200 ppm F, mostly in the form of CaF2 and chlorine-containing silicate phases.

  • Applications of molecularly imprinted materials as selective adsorbents : Emphasis on enzymatic equilibrium shifting and library screening
  • 1998
  • Ingår i: Chromatographia. - : Vieweg Verlag. - 0009-5893. ; 47:7-8, s. 465-469
  • Tidskriftsartikel (refereegranskat)abstract
    • Molecular imprinting is an attractive method for producing highly selective adsorbents, and several new and potentially useful applications based on molecularly imprinted polymers (MIPs) have been described in recent years. In this article, we highlight some of the areas where these materials have found application, and also describe some new fields of application where the selectivities of imprinted materials can be gainfully employed, for example as binding matrices in the screening of combinatorial libraries, and as auxiliary agents in enzymatic syntheses.

  • Chiral recognition by molecularly imprinted polymers in aqueous media
  • 1998
  • Ingår i: Chromatographia. - : Vieweg Verlag. - 0009-5893. ; 48:3-4, s. 197-202
  • Tidskriftsartikel (refereegranskat)abstract
    • Molecularly imprinted polymers were prepared using 2-vinylpyridine and/or methacrylic acid as functional monomers in a self-assembly imprinting protocol. The resulting polymers were analyzed in aqueous media, and the effects from the pH of the mobile phase and the degree of added organic solvent were investigated. The results are indicative of the importance of ionic bonds in conjunction with hydrophobic interactions in the formation of the complexes between the analyte and the polymers.
