Preparation and characterization of double imine bridged mesoporous silica
摘要
Abstract
Using self-made double imine silane coupling agent and ethyl silicate as silicon source,cetyl trimethyl ammonium bromide/sodium polyacrylate(CTAB/PAANa)as hybrid template agent,we synthesized double imine bridged functionalized mesoporous materials through copolycondensation method. And the structure of synthesized silicas were characterized by fourier transform infrared spectroscopy(FTIR),N2 adsorption-desorption,X-ray diffraction assay(XRD),scanning electron microscopy(SEM)and transmission electron microscopy(TEM). Besides,the effects of dosage of sodium polyacrylate(PAANa)on its structure and morphology were emphatically investigated. The silicas were then applied in adsorption of heavy metal ions. The result showed that amount of PAANa had an effect on the specific surface area,pore volume and the degree of order of mesoporous materials. While the dosage of PAANa was 0.01%,mesoporous silicone(PMOS0.01)showed good morphology and degree of order. Moreover,under acidic condition,the adsorption capacity of Cr (Ⅵ) was 289.24mg/g,while that of Cu (Ⅱ) was 276mg/g under alkaline condition.关键词
