摘要
柚子皮常被作为一种农林生物质废弃物,不仅是资源的浪费,同时还造成环境的污染。但其因含有大量纤维组织和微孔,同时存在大量的羟基、羰基、醛基、羧基等官能团,使其对物质的吸附有明显的优势,成为当前备受关注的潜在生物吸附材料。本文结合近年来国内外对柚子皮作为生物吸附剂在改性方法方向的研究进行了综述,结果表明,通过用有机酸、无机酸、无机碱、有机碱或无机盐对其进行改性后,均明显提高了其对重金属、染料、烟碱、苯酚以及一些诸如CO的气体分子的吸附,使其极有潜力成为环境友好型的吸附材料。
Pomelo peel is used as a kind of agricultural and forestry biomass waste,is not only a waste of resources,but also cause environmental pollution.However,because it contains a large number of fibrous tissues and micropores,as well as a large number of hydroxyl,carbonyl,aldehyde,carboxyl and other functional groups,it has obvious advantages in the adsorption of substances,and has become a potential biosorption material that has attracted much attention at present.In this paper,the research on the modification methods of pomelo peel as biological adsorbent at home and abroad in recent years was reviewed.The experimental result indicated that,it can be modified with organic acid,inorganic acid,inorganic base,organic base or inorganic salt,and the adsorption of heavy metal ion,dyes,nicotine,phenol and some gas molecules such as CO can be significantly improved,which makes it have great potential to be an environment-friendly adsorption material.
