摘要
红蓼是一种药用植物,药用后的红蓼残渣表面粗糙,内部疏松多孔,是一种较好的吸附载体。用冰乙酸对药用后的红蓼残渣进行改性处理,用改性后的红蓼残渣对废水中Cu^(2+)进行循环吸附研究。ICP分析表明,冰乙酸改性之后,红蓼残渣对废水中Cu^(2+)的吸附效率达到95.6%,远高于未改性红蓼残渣的吸附效率(59.2%)。3次循环吸附后,吸附效率仍达到87.3%。结果表明,对药用后的红蓼残渣进行酸改性制得的吸附材料具有很好的吸附效果。
Polygonum orientale is a kind of medicinal plant. The residue of Polygonum orientale has rough surface and porous interior. It is a good adsorption carrier. The residue of Polygonum orientale was modified by glacial acetic acid. The eyelie adsorption of Cu^2＋ in wastewater by the residue of Polygonum orientale is studied. ICP analysis showed that after glacial acetic acid modification, the adsorption efficiency of Polygonum orientale on Cu^2＋ in wastewater reached 95.6% , which is nmeh higher than that of unmodified Polygonum orientale （59.2%）. After 3 cycles of adsorption, the adsorption efficiency still reaches 87.3%. The results show that the adsorption material prepared by acid modification of the Polygonum orientale residue after medicinal has a good adsorption effect.
