| Abstract | ||
| Lignin/graphene-oxide/polyurethane composite was synthesized in order to evaluate its performance as an adsorbent for polynuclear aromatic hydrocarbons PAHs. The sequence of this process are lignin extraction and graphene-oxide preparation as a precursor for lignin/graphene-oxide/polyurethane composites synthesis. Characterization of this composite was carried out using elemental analysis, FTIR, X-ray, gel permeation chromatography GPC, and transmission electron microscopy TEM. An experimental design according to the Taguchi orthogonal array approach using Minitab software was carried out to enables the effect of factors on the response to be ascertained and identifies the optimal experimental conditions with the least variability. The efficiency of this composite towards polyaromatic removal was investigated using high performance liquid chromatography HPLC and compared to that obtained for the precursor materials. i.e., lignin and graphene oxide. | ||
