Short-chain imidazolium-based ionic liquids (IBILs) substituted by Me groups are highly water-soluble and have the potential risk of entering the water environment with wastewater. In this work, the structure-dependent Fenton reactivity and degradation pathway of methylimidazolium ionic liquids were investigated, including the influence of the proton activity and structural symmetry of IBILs. The chem. reactivity of specific sites (atoms) was quant. predicted by a condensed Fukui function (fA-). Aprotic IBILs ([DMIM][BF4] and [TMIM][BF4]) were more resistant to the •OH attacks than protic IBILs ([HHIM][BF4] and [HMIM][BF4]) because deprotonation reduced the fA- value of the attack sites. Structural symmetry increased the initial rate of the total organic carbon (TOC) reduction (k0,TOC) due to the existence of sym. Fenton reaction sites. Trimethyl-substituted [TMIM][BF4] showed the lowest TOC removal efficiency and k0,TOC presumably because the C2-Me substitution greatly weakened the fA- value of C2. The plausible mineralization pathways were proposed on the basis of gas chromatog. coupled with mass spectrometry analyses. The more Me substitution resulted in weaker Fenton reactivity but more oxidation pathways. For [TMIM][BF4], C2-Me reduced the Fenton reactivity of the imidazolium skeleton but increased the oxidation opportunities of dual N-methyls. The Fenton reactivity of methylimidazolium ionic liquids (ILs) is regulated by the proton activity and structural symmetry of ILs.
