【摘要】 以酶解提制烟碱后的烟渣和电解锰渣回收锰为原料,制备具备磁性和发达孔隙的活性炭。利用氮气吸附技术、红外光谱(FTIR)表征与分析了活性炭表面的孔隙结构和物化性质,考察了活性炭对亚甲基蓝的吸附性能和磁学性能。结果表明:以Mn/C基质废弃物为原料制得活性炭具有磁学性能;适量锰的添加有利于活性炭微孔的形成和发育;采用一步焙烧法有助于磁化物和活性炭基体相互作用形成化学键合,提高饱和磁化强度,实现废弃资源的充分利用。更多还原

【Abstract】 Activated carbon,which has magnetic and developed porosity,was prepared from the electrolytic manganese residue and the waste tobacco after extracting nicotine with microbial enzymatic.Surface properties and structure of the activated carbion were characterized by N2 adsorption isotherm and FTIR,and the absorption and magnetic properties of them were determined by methylene blue.The results show that activated carbon of the Mn/C raw material has magnetic properties.At the same time,a proper amount of Mn in the raw material makes it possible to grant the activated carbon with a higher magnetism and a bigger magneto conductivity.Chemical bonding is formed and saturation magnetic intensity increases in the interaction of magnetic materials and activated carbon.This research results would benefit the resource utilization of the waste tobacco and electrolytic manganese residue.更多还原
