| 摘 要： | INTRODUCTIONToday, the world's industry is utilizing less than 10% of biomass of raw materials from plantation 1]. Agricultural residues, such as cereal straws are important and abundant renewable organic resources of energy and production of a diversity of chemicals, including ethanol production 2], activated carbon 3] and ion exchangers 4]. Many other applications for Cereal straws are in the process of being developed.In china, wheat, maize and sorghum are the three major crops, w…

| Abstract: | Various lignocellulosic materials such as wood, agricultural and forest residues has the potential to be valuable substitute for, or complement to, commercial sorbents for removing heavy metal ions or dyes from waste water or spilled oil from inland water or sea. More than 9 million tons of straw pulp are produced annually in china, which account for about 90% of the world's total straw pulp. However, huge quantity of remain straw is not used as industrial raw material and is burnt in the fields or on the side of road. These resources can be chemical modified such as acetylation. Modified straws have the characteristics of low cost, high capacity, quick uptake, and easy to desorb. This paper reviews the current status of the technology for modified agricultural residues, which focus on hemicellulose and cellulose. The potential of these natural sorbents in main industry is also indicated. |
