【摘要】 生物质炭作为极具潜能的吸附材料,通过改性能极大提高其吸附效果。阐述了三方面的改性方法,分别为生物质炭的活化、生物质炭负载金属与金属氧化物和功能化生物质炭,对比了改性前后对Cd的吸附效果,总结了各改性生物质炭的吸附机理,展望了今后生物质炭的研究点。更多还原

【Abstract】 As a potential adsorption material,biochar can greatly improve its adsorption effect by improving its properties.Three modification methods are described,the activated biochar,biochar was loaded with metal and metal oxide,and the functional biochar,the adsorption effect of biochar on Cd was compared before and after modification,the adsorption mechanism of modified biomass carbon was summarized,the research points of biomass carbon in the future are prospected.更多还原
