A facile and one‐pot strategy for the preparation of novel diamino‐functionalized hollow siliceous spheres (DAF‐HSS) is suggested. Field‐emission scanning electron microscopy (FE‐SEM) images of DAF‐HSS showed a monodispersed hollow sphere morphology. Also, TEM images revealed that the DAF‐HSS has a porous structure with parallel semi‐long‐range channels. DAF‐HSS material was used as an adsorbent for the removal of hazardous monocationic dyes in aqueous solution. Neutral red (NR) and crystal violet (CV) were selected as model compounds. Isotherm and kinetic studies were carried out and their different linear forms were applied and compared. The equilibrium data fitted better with the Langmuir model.

介孔结构的空心硅质球对染料的吸附

建议使用一种简便的单罐策略制备新型的二氨基官能化空心硅球（DAF-HSS）。DAF-HSS的场发射扫描电子显微镜（FE-SEM）图像显示出单分散的空心球形态。另外，TEM图像显示DAF-HSS具有带有平行半远程通道的多孔结构。DAF‐HSS材料用作吸附剂，用于去除水溶液中的有害单阳离子染料。选择中性红（NR）和结晶紫（CV）作为模型化合物。进行了等温线和动力学研究，并应用了它们的不同线性形式并进行了比较。平衡数据更符合Langmuir模型。
