| 摘 要： | 对具有催化功能的负载Fe（Ⅲ）的活性炭进行了表征，与母体活性炭相比，其比表面积以及微孔体积均有所下降，酸性官能团的量有所增加；考察了普通浸渍法和超声浸渍法制备的双功能活性炭对毒死蜱的吸附和降解性能，结果表明，双功能活性炭对毒死蜱的吸附量有所降低，但对毒死蜱的降解能力增强，超声浸渍法所制备的活性炭对毒死蜱的降解能力要优于普通浸渍法所制备的活性炭。

| Abstract: | The catalytic function of activated carbon supported by Fe （ III ） were characterized, their specif- ic surface areas and micropore volumes decreased, but the numbers of acidic functional groups increased com- pared with original activated carbon. Adsorption and degradation of chlorpyrifos were investigated on the activated carbons prepared by conventional and ultrasonic impregnation method. The results showed that the adsorption ca- pacity of chlorpyrifos decreased on the dual function activated carbons but the degradation properties were im- proved. Degradation properties of chlorpyrifos on the activated carbons prepared by ultrasonic immersion were su- perior to the activated carbons prepared by conventional impregnation. |
