中空管状碳化玉米秸秆吸附剂的制备及吸油性能研究

Preparation and Oil Absorption Properties of Carbonized Cornstalk Adsorbent with Hollow Tubular Structure

随着经济的快速发展,环境污染呈逐年增长态势,突发性溢油事故以及石油化工行业生产过程中产生的含油废水给环境带来巨大的压力.发展有效且廉价的石油吸附剂成为了极具价值的研究方向.碳化玉米秸秆是一种天然的具有中空结构的石油吸附材料.它不仅可以回收利用,而且具有良好的生物降解性.玉米秸秆在不同温度下碳化,可以制成碳化玉米秸秆.此种碳化玉米秸秆对氯仿的最大吸附量可达到35 g/g,此外,它还具有良好的可重复使用性和稳定性.

With the rapid development of economy,the environmental pollution is increasing year by year. The sudden oil spill and oily wastewater in petrochemical industry have brought tremendous pressure to the environment. Effective and cheap oil adsorbents have become a promising research field. Carbonized corn stalk （CCS） is a natural oil sorption material with hollow structure. It can be recycled and has good biodegradability. Carbonized corn stalk was prepared from corn straw at different temperatures. The maximum oil sorption of CCS to chloroform was 35 g/g, which has good reusability and stability.
