摘　　要：合成了一种醚基功能化的酸性离子液体,以葡萄糖为碳源、离子液体为溶剂和碳化助剂,80℃、常压下,葡萄糖碳化得到离子液体-碳纳米颗粒发光体系。所得离子液体-碳纳米颗粒发光体系对三价铁离子具有高度选择性荧光猝灭效应,可用于直接检测高浓度铁离子废水,其线性范围为1×10-4~1×10-3mol/L,线性回归系数R2=0.996 1。A kind of ether functionalized acidic ionic liquids was synthesized. An ionic liquid-carbon nanoparticles mixtures was obtained at 80 ℃ and 0. 1 MPa. The mixture has high fluorencence quenching selectivity for Fe^3＋and good environmental stability. It can be directly used in the detection of high concentrate Fe^3＋ in waste water. The liner range is from 1 × 10^（- 4）～1 × 10^（- 3）mol / L and the liner regression coefficient is 0. 996 1.
