Research Abstract

Novel ionic liquids consisting of superoxide anions and monovalent cationic crown-ether complexs were investigated as reusable oxidizing agents for wasterwater treatment. The resulting yellowish ionic liquids had melt points near ambient temperature. Use of glymes, i.e. linear ethers, instead of crown ethers, i.e. cyclic ethers, did not give ionic liquids. The coordination environment of the cationic complexs in the ionic liquids was invastigated by Raman spectroscopy. The presence and long-term stability of superoxide anions were examinded with a series of magnetization measurements. The effect of superoxide anions as oxidizing agents was evaluated by using the degradation of chemically stable imidazolium and phosphonium ionic liquids in the presence of superoxide anions as a model reaction.
