摘要 选用不同炭化温度的竹炭,研究其对单一和混合重金属离子的吸附性能。结果表明:竹炭对重金属离子吸附存在物理和化学吸附,其吸附性能与其比表面积、孔径及pH等有关;不同炭化温度竹炭对重金属的吸附有选择性,炭化温度为800℃的竹炭对Hg2+、Pb2+、Cr6+吸附效果较好,炭化温度为1 000℃的竹炭对Cd2+吸附效果较好;竹炭吸附混合重金属离子存在协同和阻碍两方面的效应,与单一离子相比,竹炭在混合重金属离子溶液中对Pb2+、Hg2+、Cr6+吸附率增加,而对Cd2+的吸附率却减少。 In this paper, bamboo materials was carbonized at varying temperature and used to adsorb single and mixture solu- tions of heavy metal ions. The results showed that bamboo charcoal has physical and chemical adsorption. The absorption properties were related to the specific surface area, pore size and the pH value. Absorption rate of bamboo charcoal was en- hanced with the impregnated time. Bamboo charcoal adsorption of heavy metal ions had selectivity. Bamboo charcoal with car- bonization temperature of 800~C had better adsorption for Hg2+ , Pb2+ , Cr6~ , but bamboo charcoal which was carbonized at 1 000℃ had good adsorption for Cd2 + . When the mixture of several metal ions coexisted, the property of bamboo charcoal ad- sorption for heavy metal ions had the characteristics of synergy and impede. If it was compared with a single heavy metal ions, the adsorption rates of Pb2+ , Hg2. , Cr6+ increased and the adsorption rate of Cd2+ decreased.
