【摘要】 将市售粉状活性炭用16%硝酸进行氧化,再用0.1mol.L-1的氢氧化钠进行处理,制得化学改性活性炭,并对其吸附性能进行了研究.实验结果表明,改性后的活性炭较改性前对Cu2+离子的吸附能力提高60%以上.更多还原

【Abstract】 The chemical modified activated carbon is obtained by oxidizing raw activated carbon with 16% nitrate acid and being treated with 0.1mol/L sodium hydroxide. This paper studies the adsorption of copper (II) from aqueous solutions using this chemical modified activated carbon and the result shows that the adsorption amount of copper (II) by chemical modified activated carbons 60% higher than that by raw activated carbon.更多还原
