New organic-inorganic hybrid materials were prepared by covalently anchoring 1-furoyl thiourea on mesoporous silica (SBA-15). By means of various characterization techniques (X-ray diffraction, nitrogen adsorption-desorption, thermogravimetric analysis, and FTIR spectroscopy) it has been established that the organic groups were successfully anchored on the SBA-15 surfaces and the ordering of the inorganic support was preserved during the chemical modifications. The hybrid sorbents exhibited good ability to remove Hg(II) from aqueous solution. Thus, at pH 6, the adsorption capacity of mercury ions reached 0.61 mmol g(-1).
新的有机-无机杂化材料是通过将 1-糠酰基硫脲共价键合到介孔硅（SBA-15）上制备的。通过各种表征技术（X 射线衍射、氮气吸附-脱附、热重分析和傅里叶变换红外光谱），已经证实有机基团成功地固定在 SBA-15 表面上，并且在化学修饰过程中保持了无机载体的有序性。杂化吸附剂具有良好的从水溶液中去除 Hg(II)的能力。因此，在 pH 值为 6 时，汞离子的吸附容量达到 0.61mmol/g。
