| 摘 要： | 为了提高活性炭纤维(ACF)对水体中重金属铅离子的吸附性能,采用浓HNO3对ACF进行了氧化改性,并采用静态吸附法,考察了不同实验条件对样品吸附铅离子的影响。实验结果表明:1.氧化改性后样品对铅离子的吸附速率非常迅速,吸附平衡时间仅需要5 min。2.氧化改性后ACF在较宽的pH值范围内保持着对铅离子较高的吸附性能。

| Abstract: | For further improving its adsorption capacity,ACF was modified by oxidation with concentrated nitric acid,and then under the varies experiment conditions,we investigate the properties of adsorbing Pb~(2 ) of ACF and oxidized ACF.The results showed that all samples had a rapid adsorption rates(the equilibration time of adsorption was only(5 min)),and the oxidized ACF had good adsorption properties in a quite wide range of pH values. |
