角蛋白基生物炭对废水中重金属Ni(Ⅱ)的吸附性能研究
Studies on the Adsorption Properties of Keratin Biochar on Heavy Metal Ni(Ⅱ) in Sewage Water
摘要
Abstract
The surface analysis and adsorption application of keratin base biochar produced from the waste hair of life waste has provided a new idea and new method for the domestic waste treatment and resource utilization.Through the SEM analysis of biochar,and the study of the adsorption properties of biochar on heavy metal Ni (Ⅱ) in wastewater,the surface performance characteristics of the keratin base biochar and the dynamic and thermodynamic adsorption curve of it on heavy metal in wastewater were determined.Surface structure of keratin base biochar has developed micropores,mesopores,and macropores,the Ni (Ⅱ) adsorption kinetics accords with secondary dynamics equation,dominated by chemical adsorption.The Langrnuir and Freundlich model fitting curves can well describe the isothermal adsorption of keratin biochar on Ni (Ⅱ).The obtained keratin biochar has certain adsorption effect on wastewater containing heavy metal Ni(Ⅱ).It can provide reference for the application of urban sludge composting,the adjustment of organic carbon content of soil,and the adsorbent of atmospheric pollutants,which has certain practical significance.关键词
