Fabrication of Carboxymethyl Cellulose Supported Bi-Fe Nano Catalyst for the Removalof Dyes from Aqueous Medium under Direct Sunlight Radiation

Abstract

Carboxymethyl cellulose (CMC) supported Bi-Fe nanocomposite is synthesized by very simple, cost effective and environment friendly co-precipitation method. The characterization of the synthesized Carboxymethyl cellulose (CMC) supported Bi-Fe nanocomposite is performed by the help of UV-visible spectrophotometer, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectrophotometer (FTIR). The UV-visible and Fourier transform infrared spectrophotometer (FTIR) confirmed the presence of Bi-Fe nanocomposite. The X-ray diffraction (XRD) showed the structure and particle size of the prepared Carboxymethyl cellulose (CMC) supported Bi-Fe nanocomposite. The scanning electron microscope (SEM) confirmed the morphology of the structure of the nanocomposite from micrometer to nanometer. The degradation of methylene blue (MB) was done in 180 minutes. It was also very effective for the degradation of methyl orange and ortho-nitrophenol. 0.05mM solution of methyl orange was degraded up to 85% in 150 minutes and ImM solution of ortho nitrophenol was degraded up to 70 % in 30 minute. The time effect also confirmed this factor. The concentration of MB is taken as 0.01mM. In every 10ml solution 1mg of catalyst was added. Same concentration of catalyst was taken for MO and ortho-nitrophenol. The degradation done by the carboxymethyl cellulose (CMC) supported Bi-Fe nanocomposite was up to 82% for MB, 85% for MO and 70% for orthonitrophenol as confirmed by UV-visible spectrophotometer
