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。
Nicotine nicotine after enzymatic hydrolysis of manganese slag and manganese recovery Manganese as raw material, prepared with magnetic and developed pore activated carbon. The pore structure and physicochemical properties of activated carbon were characterized and characterized by nitrogen adsorption and FTIR. The adsorption and magnetic properties of methylene blue on activated carbon were investigated. The results show that the activated carbon prepared from Mn / C substrate waste has magnetic properties. The addition of appropriate amount of manganese is favorable for the formation and development of micropores in activated carbon. The one-step calcination method can help the interaction between the magnetite and the activated carbon matrix to form chemical bonds Together, improve the saturation magnetization, to achieve full use of abandoned resources.
