CO2 adsorbents with Polyethyleneimine-g-Wheat Husk were prepared. The preparing method was performed in two step. In first step, epoxy group was introduced on surface WH particles using epichlorohydrin as W-ep. In second step, the branched PEI was reacted with epoxy group on W-ep, then it was performed by Schiff’s reaction with amine of PEIs and aldehyde of glutaraldehyde. The characteristics of PEI-grafted WH and raw WH were evaluated using Fourier Transform Infrared spectroscopy(FT-IR), X-ray Photoelectron Spectroscopy(XPS) and Scanning Electron Microscope(SEM). The CO2 adsorption of the WH and W-ep/PEI was measured by Thermogarvimetric Analyzer(TGA) observation. |
