Modified mesoporous silicas were examined as adsorbents for efficient removal of model pollutants from wastewaters. Functionalized SBA-15 materials for capture of cationic pollutants such as metal cations and anionic dyes were obtained using post-synthesis grafting method. Large organic ligands containing acetyloacetone, 2-aminopyridine, 2-aminothiazole and 2-aminobenzothiazole groups were incorporated into the adsorbents' structure. The adsorption capacities reached levels of 38.6, 43.1, 64.3, 68.6 and 88.9 mg g⁻¹ for Cu²⁺, Rose Bengal, Congo Red, Levafix Amber CA gran and Methyl Orange, respectively. Moreover, the adsorption efficiency depended on a type of the model molecule and a type of the surface chelating group. The pores' size and the pores' volume of the hybrid materials before and after adsorption was determined in hydrated state using thermoporometry. For the first time, by means of this methodology, it was possible to propose a model of interactions between the adsorbed molecules and the grafted organosilanes. Adsorption of organic dyes resulted in most cases in formation of J-aggregates.

研究了改性介孔二氧化硅作为吸附剂的有效去除废水中模型污染物的能力。使用合成后接枝方法获得了用于捕获阳离子污染物（例如金属阳离子和阴离子染料）的功能化SBA-15材料。含有乙酰丙酮，2-氨基吡啶，2-氨基噻唑和2-氨基苯并噻唑基团的大型有机配体被合并到吸附剂的结构中。Cu ²⁺的吸附容量达到38.6、43.1、64.3、68.6和88.9 mg g ^-1，玫瑰红，刚果红，Levafix Amber CA gran和甲基橙。此外，吸附效率取决于模型分子的类型和表面螯合基团的类型。使用热孔法在水合状态下测定吸附前后杂合材料的孔大小和孔体积。通过这种方法，有可能首次提出吸附分子与接枝有机硅烷之间相互作用的模型。在大多数情况下，有机染料的吸附导致J聚集体的形成。
