摘要
竹材热分解得到的竹炭具有较高的孔隙度和比表面积,其良好的性能引起了人们的广泛关注。本文综述了近年来关于竹炭性能和应用的研究报道,着重介绍了竹炭的吸附性能,电、磁性能及其在各领域的应用状况,如吸附大气和水环境中的无机、有机污染物;以竹炭为原料生产电磁屏蔽材料、静电屏蔽材料和电热材料,同时,可通过重整孔结构和修饰孔表面等方法来提高竹炭的吸附能力。另外,竹炭的多孔性能使不同材料负载其上成为可能,由此可充分发挥两种材料的优势,使得竹炭基复合材料具有很广的应用前景。本文还涉及竹炭吸附热力学、动力学及再生研究、改性竹炭等内容,并指出今后竹炭研究的发展趋势。
Bamboo charcoal, produced from the thermal decomposition of bamboo wood, has attracted much attention from many fields in recent years. This paper reviews the properties and applications of bamboo charcoal, focusing on the aspects of adsorption, electrical and magnetic properties, such as the adsorption of the inorganic and organic substance in atmosphere and water, its use as an electromagnetic shielding material, an electrostatic screening material, and a thermo electric material. The adsorption property of bamboo charcoal can be improved by reforming the pore structure and the modification of the pore surface, and different materials can be loaded on it because of its poriness to combine the advantages of different materials, so, the composite based on bamboo charcoal is widely used in different areas. Besides, this paper also discusses the kinetics and thermodynamics for adsorption by bamboo charcoal and the regeneration of bamboo charcoal, together with the development trend of bamboo charcoal researches.
