摘  要：本论文以改性介孔硅基材料SBA-15（SA-SBA-15）作为课题研究对象，通过使用N2吸附/脱附等温线（BET）、X射线衍射(XRD)、透射电子显微镜(TEM)、差热-热重（DTA-TG）、傅立叶红外(FT-IR)等对改性介孔硅基材料SBA-15进行了表征。分析结果表明改性介孔硅基材料SBA-15的表面可以很好的包裹席夫碱。然后对改性介孔硅基材料SBA-15进行水体中Cu2+的吸附实验，发现其对铜离子的吸附能力较强，吸附剂用量达到50 mg时，实验条件下，吸附容量达到饱和；Cu2+的吸附随pH呈波动性变化，pH为5时处理效果最好；经过硝酸处理的SA-SBA-15在经历三个再生周期后仍然保持良好的吸附能力。68681

Abstract: Popular materials Mesoporous Silica materials SBA-15 were as the research object in this paper. Mesoporous Silica materials SBA-15 were characterized by the images of DTA-TG, X-ray diffraction patterns (XRD), transmission electron microscope (TEM), Fourier transform in-frared (FT-IR), adsorption and stripping isotherm of nitrogen. This experimental process indicates that Mesoporous Silica materials SBA-15 can very good pack the Schiff base. Then we research the absorption ability of the metals, we discover that they have a very good absorption toward inorganic metal copper ion. When the adsorbents are about 50 mg, the adsorption capacity is in the highest point. The adsorption of copper ion will change with the pH. There will have a effective treatment effect at 5. The SA-SBA-15 treated with nitric acid still keeps good adsorption capacity after three regeneration cycle.
