Polymer-cellulosic-clay and polymer-cellulosic-zeolitic biocomposites for the removal of methylene blue in aqueous solution
Published online by Cambridge University Press: 19 November 2019
Abstract
In the present investigation, biocomposites were synthesized from a polymeric alginate matrix in which the carrot residue and a natural bentonite (ANat / Bio) or an iron-modified clinoptilolite-type zeolite (ZFe / Bio) were supported. Their properties were evaluated adsorbents in contact with aqueous solutions of methylene blue (MB). In the first hour of contact, 46% removal was obtained for the ZFe / Bio biocomposite and 60% for the ANat / Bio biocomposite; reaching 100% removal for the ZFe / Bio biocomposite and 98% for the ANat / Bio biocomposite after 24 hours. The biocomposites were characterized by Scanning Electron Microscopy (SEM) and Fourier Transformed Infrared Spectroscopy (FTIR).
