Synthesize of β-cyclodextrin functionalized dendritic fibrous nanosilica and its application for the removal of organic dye (malachite green).

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.
