Paper Title:
Chemically Modification to Corn Stalk as a Natural Material for Oil Absorption
  Abstract

A series of natural materials used for oil absorption based on corn stalks have been prepared by acylation grafting with propionic anhydride in a solvent-free system at 100 and 140 °C for 2-6 h. It is found that the oil (benzene) sorption capacity of the grafted corn stalks is about 8.5- 12.6g/g (in 15 minutes), and the grafted material is significantly more hydrophobic than the raw corn stalks. The grafted corn stalk float on the surface of water, as the oil, can be easily to be removed when the application is completed. Fourier infrared (FT-IR) analysis is used to confirm the chemical reaction which takes place between corn stalks and propionic anhydride. Scanning electron microscope (SEM) analysis is used to determine the structure of the grafted corn stalk material.
