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 m /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.
从工业废水中去除染料已经成为一个重要的问题。高可见度、不理想和难处理是染料的重大环境问题。在本工作中，合成了β-环糊精功能化的 KCC-1（KCC-1-NH-β-CD），并将其用于去除危险的孔雀石绿。为了研究合成纳米吸附剂的形貌，通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）获得了样品表面的形貌。此外，通过傅里叶变换红外光谱（FTIR）证实了 KCC-1 与β-环糊精的功能化。通过氮气吸附/解吸分析（BET 方程）验证了 KCC-1 的结构特性。利用紫外-可见光谱研究了 KCC-1-NH-β-CD 对孔雀石绿的去除作用。计算得到吸附剂的比表面积为 140 m²/g，可以表明合成的纳米吸附剂具有很高的去除效率。需要注意的是，所采用的纳米吸附剂的吸附容量超过 95%，这可以归因于β-环糊精功能化 KCC-1 的高孔隙率。
