摘要
生物炭是通过生物质原材料制备的富炭产物。生物炭因具有比表面积大、结构多孔和官能团丰富等优点,能够有效吸附水中有机污染物。当生物炭经功能化改性后,可作为性能优越的功能材料,能够高效降解水中的有机污染物。为了深入探究生物炭改性材料对水体有机污染物的去除作用,在概括生物炭吸附/降解水体有机污染物的一般机理的基础上,重点对生物炭改性方法及其对有机物的吸附/降解机制进行系统总结并作出展望。
Biochar is a carbon-rich product prepared from biomass raw materials.Biochar can effectively adsorb organic pollutants in water due to its advantages of large specific surface area,porous structure and abundant functional groups.Through functional modification,biochar can be used as a functional material with superior performance,which can efficiently degrade organic pollutants in water.In order to deeply explore the removing effect of biochar modified materials on organic pollutants in water,the biochar modification method and its adsorption/degradation mechanism of organic matter were mainly concluded systematicly and prospect was made,based on summarizing the general mechanism of biochar adsorption/degradation of organic pollutants in water.
