Pectin-crosslinked-guar gum/SPION nanocomposite hydrogel for adsorption of m-cresol and o-chlorophenol

Pectin-crosslinked-guar gum/superparamagnetic iron oxide (Pc-cl-GG/SPION) nanocomposite hydrogel have been fabricated through co-precipitation/polymerization method. During this process, methylenebisacrylamide was used as a sole cross linker and it plays a vital role for the enhancement of mechanical stability of the nanocomposite hydrogel. This magnetic nanocomposite hydrogel was characterized using various techniques such as Fourier-Transform Infrared (FTIR) Spectroscopy, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) Transmission Electron Microscopy (TEM) and Vibrating Sample Magnatometery (VSM). The prepared nanocomposite hydrogel was subjected to adsorption of organic pollutants from aqueous system. Experimental results indicated that Langmuir isotherm fitted best to the adsorption of MC and OCP onto Pc-cl-GG/SPION nanocomposite hydrogel. Maximum adsorption capacity of Pc-cl-GG/SPION nanocomposite hydrogel has been found to be 176.1 and 75.6 mg/g for m-cresol and o-chlorophenol, respectively.
