Dye removal from industrial waste water has become an important issue. The highvisibility, undesirability and recalcitrance are the significant environmental problemfor the dyes. In the present work,β‐cyclodextrin functionalized KCC‐1 (KCC‐1‐NH‐β‐CD)was synthesized and utilized to the removal of hazardous malachite green. In order to study the morphology of the synthesized nano adsorbent, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were obtained from the surface of the sample. Additionally, the functionalization of KCC‐1 with β‐cyclodextrin was confirmed with Furrier Transform Infrared spectroscopy (FTIR). The textural property of KCC‐1 was verified using nitrogen adsorption/ desorption analysis (BET equation). UV‐Vis spectroscopy utilized for the investigation of malachite green by KCC‐1‐NH‐β‐CD. Specific surface area of the adsorbent was calculated to be 140 m2/g and it can be stated that the synthesized nano adsorbent has high removal efficiency. It should be noted that the adsorption capacity of the employed nano adsorbent was more than 95%, which could be attributed to high porosity of β‐cyclodextrin functionalized KCC‐1.

β-环糊精功能化树枝状纤维纳米二氧化硅的合成及其在去除有机染料(孔雀石绿)中的应用。

从工业废水中去除染料已成为一个重要问题。高能见度、不受欢迎和顽固是染料的重要环境问题。在目前的工作中,β-环糊精功能化的 KCC-1(KCC-1-NH- β -CD)被合成并用于去除有害的孔雀石绿。为了研究合成的纳米吸附剂的形貌,从样品表面获得了扫描电子显微镜(SEM)和透射电子显微镜(TEM)。此外,KCC-1 与β-用傅里叶变换红外光谱 (FTIR) 证实了环糊精的存在。使用氮吸附/解吸分析(BET 方程)验证了 KCC-1 的结构特性。紫外-可见光谱用于通过 KCC-1-NH- β -CD研究孔雀石绿。吸附剂的比表面积计算为140 m 2 /g,可以说合成的纳米吸附剂具有很高的去除效率。应该指出的是,所采用的纳米吸附剂的吸附容量超过 95%,这可能归因于β-环糊精功能化 KCC-1 的高孔隙率。
