随着全球经济的不断发展,煤、石油、天然气等不可再生资源的日益消耗,促使对生物质资源需求的日益增加,半纤维素等农林废弃物再生资源化利用已经成为了一种重要的途径。基于此,简述了半纤维素的改性以及在医药、造纸助剂、塑料、污水处理等多个领域的运用。 With the continuous development of the global economy, the increasing consumption of non-renewable resources such as coal, petroleum and natural gas has led to the increasing demand for biomass resources and the utilization of renewable resources such as hemicellulose and other agricultural and forestry wastes has become an important approach . Based on this, a brief description of the modification of hemicellulose and its application in many fields such as medicine, papermaking auxiliaries, plastics, sewage treatment and so on is given.
