摘要
本文以生物基材料为原材料制备胶原基多孔炭,生物质基材料中的氨基酸既是碳源,又是氮源,可以使制得的胶原基多孔炭材料富含氮。多孔炭富含氮不仅可以提高吸附选择性还可以增大吸附量。根据多孔炭的吸附性能,可以将其用来吸附含硫废水中的硫离子。根据Langmuir等温吸附模型,多孔炭最大吸附量达到254.69mg/g,且吸附结果符合二级动力学模型。
Collagen-based porous carbon was prepared by biomaterials in this paper.Amino acids in biomaterials could be used as both carbon source and nitrogen source,so that the as-prepared collagen-based porous carbon material rich in nitrogen.The porous carbon rich in nitrogen not only improved the adsorption selectivity,but also increased the capability of adsorption.The sorption properties of porous carbon leaded to the application in adsorption for sulfur-containing wastewater.According to the Langmuir isothermal adsorption model,porous carbon maximum adsorption capacity reached 254.69mg/g and adsorption behavior accorded with the pseudo-second kinetic model.
