β- Cyclodextrin Functionalized KCC-1: A Novel Adsorbent for Separation of Organic Compounds

Dendritic nano silica fibers are of remarkable interest, which have been recently discovered by Polshettiwar et al [1]. These kind of nano materials possess high textural property and well defined morphology and are generally called as KCC-1. The aforementioned properties are a good stimulant to utilize this mesoporous material as a support for catalysis, adsorption of gas and solar energy, and bio medical applications [2]. These Nanomaterials have a convergent needle like morphology, which is demonstrated in Fig, 1 and has been compared morphologically with MCM-41 [3]. The present study is aimed to prepare β-Cyclodextrin functionalized KCC-1 and its utilization in removal of hazardous dyes such as malachite green. In order to study the morphology of the synthesized nano adsorbent, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were achieved from the surface of the sample. Additionally, the functionalization of KCC-1 with β-Cyclodextrin was confirmed with Furrier Transform Infrared spectroscopy (FTIR). 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. The textural property of KCC-1 was verified using nitrogen adsorption/ desorption analysis (BET equation). Specific surface area of the adsorbent was calculated to be 140 m2/g. Consequently, it can be stated that the synthesized nano adsorbent has high removal efficiency.
