摘要

这项研究对氧化锆、氧化铝和二氧化硅的形态进行了研究,并在这些氧化物上对驱避剂 N,N-二乙基-3-甲基苯甲酰胺和 3-[乙酰(丁基)氨基]丙酸乙酯进行了静态吸附。结果表明,ZrO2、Al2O3 和 SiO2 苯基对驱避剂 N, N-二乙基-3-甲基苯甲酰胺(SiO2 苯基 239 毫克/克)和 3-[乙酰(丁基)氨基]丙酸乙酯(ZrO2 251 毫克/克)具有较高的吸附活性。值得注意的是,尽管 SiO2 C2 具有最大的孔体积和较高的比表面积(与所研究的其他氧化物相比),但其吸附能力明显低于其他氧化物,特别是 SiO2 苯基,这可以解释为后者中存在苯基,而苯基对排斥分子具有化学亲和力。获得的 SiO2 300 等温线也证实了它对 N,N-二乙基-3-甲基苯甲酰胺的吸附活性较低。在大多数情况下,两种驱避剂的吸附平衡都可以用 Langmuir 单分子吸附模型来描述。研究结果表明,所研究的氧化锆、氧化铝和二氧化硅可用作驱避剂的载体成分。

Study of sorption properties of zirconia, alumina, and silica in relation to repellents

In this work, the morphology of zirconia, alumina, and silicas was studied, and static sorption of the repellents N, N-diethyl-3-methylbenzamide and ethyl-3-[acetyl(butyl)amino]propionate on these oxides was carried out. ZrO2, Al2O3, and SiO2 phenyl were shown to have high sorption activity to the repellents N, N-diethyl-3-methylbenzamide (239 mg/g for SiO2 phenyl) and ethyl-3-[acetyl(butyl)amino]propionate (251 mg/g for ZrO2). Pointedly, it was found that despite having the largest pore volume and high specific surface area (compared to the other studied oxides), SiO2 C2 has a significantly inferior sorption capacity in respect to other oxides, in particular SiO2 phenyl, which can be explained by the presence of the phenyl group in the latter that has chemical affinity for repellent molecules. Obtained isotherms of SiO2 300 also confirm the low sorption activity towards N, N-diethyl-3-methylbenzamide. The sorption equilibrium for both repellents, in most cases, is described by the Langmuir monomolecular adsorption model. The obtained results suggest that the studied zirconia, alumina, and silica can be used as carrier components of repellents.

期刊介绍: Colloid and Polymer Science - a leading international journal of longstanding tradition - is devoted to colloid and polymer science and its interdisciplinary interactions. As such, it responds to a demand which has lost none of its actuality as revealed in the trends of contemporary materials science.
