摘要：

The electrochemistry and UV-vis spectroscopy of water-soluble iron tetrakis(p-sulfonatophenyl)porphyrin (Na3[FeTPPS]) have been thoroughly investigated with respect to the interaction of FeIII- and FeIITPPS with several nitrogen and sulfur donor ligands. On the basis of this information, a separation scheme for the selective removal and concentration of nitrogen heterocycles from a hydrocarbon solvent is demonstrated. This serves as a model for coal liquids polluted with polyaromatic heterocyclic compounds and illustrates the potential utilization of the process for removing environmentally hazardous materials from a variety of matrices. The process involves the use of electrochemistry to modulate the coordination of nitrogen heterocycles to FeTPPS, which serves as a carrier in a cyclic solvent extraction/release process. The modulation of the binding effectively changes the ability of an FeTPPS aqueous solution to extract and release various pollutants. The extensions of this process to other systems is also discussed. © 1990, American Chemical Society. All rights reserved.
