Fabrication of Vinyl Functionalised Multiwalled Carbon Nanotubes for the Removal of Organic Pollutant

Abstract

A novel and convenient approach for the fabrication of vinyl functionalized multiwalled carbon nanotube (MWCNT) as a sorbent for organic pollutant is described in this article. In this method, the purified MWCNT is functionalized via a non-covalent strategy using 9-vinyl anthracene, fluorescent active species. The synthesised nanotube was characterised using various techniques such as Fourier transform infrared spectroscopy (FT-IR), UV-Vis. spectroscopic analysis, scanning electron microscopy (SEM), X-ray diffraction technique (XRD), thermogravimetric analysis (TGA), transmission electron microscopy (TEM) and Raman spectroscopy. Effects of concentration, pH and time for the functionalization of MWCNTs were investigated through photoluminescence (PL) studies. The resulting vinyl functionalized MWCNT will act as a promising adsorbent for organic pollutants like p-chlorobenzoic acid.
