In this study, mesoporous silica (meso-silica) MCM-41 and those with the templates retained were synthesized and characterized. Adsorption capacities of the synthesized materials towards typical quinolone antibiotic pollutants, enrofloxacin and norfloxacin as representative, were investigated, and effects of the alkyl chain length of the templates on the adsorption capacity were evaluated. The results of this study indicated that the retained templates enhanced the adsorption capacities (Qmax) of the meso-silica MCM-41 toward hydrophobic enrofloxacin, but had an inhibitory effect on that towards hydrophilic norfloxacin, which were attributed to the hydrophobic inter-environment created by the long alkyl chains of the retained templates. Importantly, the adsorption capacity increased with the increase of the alkyl chain length of the retained templates.
在这项研究中，合成并表征了介孔硅（meso-silica）MCM-41 及其保留模板的材料。研究了合成材料对典型喹诺酮类抗生素污染物，恩诺沙星和诺氟沙星作为代表的吸附能力，并评估了模板的烷基链长度对吸附能力的影响。本研究结果表明，保留模板增强了介孔硅 MCM-41 对疏水性恩诺沙星的吸附能力（Qmax），但对亲水性诺氟沙星的吸附能力有抑制作用，这归因于保留模板的长烷基链所产生的疏水环境。重要的是，吸附能力随保留模板的烷基链长度的增加而增加。
