A Magnetically Mesoporous Silica Nanoprobe Used for Recognition and Removal of Fe^(3+)

制备了一种可用于Fe^(3+)检测和脱除的香豆素类磁性介孔硅纳米探针MMS-C,通过TEM、FT-IR、XRD、N2吸附手段表征了其结构。性能测试结果表明,MMS-C在甲醇中对Fe^(3+)表现荧光猝灭的响应和较高的识别选择性。此外,MMS-C对Fe^(3+)具有一定的脱除能力,脱除率为38.9%。

A magnetically mesoporous silica nanoprobe MMS-C based-on coumarin was prepared for the detection and removal of Fe^3＋ The MMS-C was characterized by TEM, FT-IR, XRD, N2 adsorption. MMS-C exhibited quenched fluorescence in the pres- ence of Fe^3＋and a high selectivity for Fe^3＋over the competing metal ions in methanol. Furthermore,MMS-C exhibited a removal capacity of 38.9% for Fe3 ＋ .
