| Abstract | 本文详细研究了以山渣核为原料制取高强度、高吸附性能活性炭进而利用这种活性炭浸渍铁离子并氧化处理制取磁性活性炭的工艺，该工艺既简单易行，又便于应用推广。研究表明：升温速度对活性炭制备没有显著影响，900 ℃炭化并活化110mins可制得碘值达1010mg/g的高强度活性炭。赋磁过程中浸渍液的PH值和铁的电荷数对活性炭吸附有重要影响，活性炭在中性溶液中的吸附量最大，在碱性溶液中吸附最小；同一离子浓度下，活性炭对Fe~(+3)的吸附量大于对Fe~(+2)的吸附量。活性炭赋磁不影响其吸金能力，与市售活性炭相比，4.5小时后的吸金量基本相同，吸金后磁性活性炭的磁性变化不大。 |
| Other Abstract | One kind of magnetical activated carbon was made through the process described in detaits here. Activated carbon with high hardness and high absorptivity was made from hawstone、impregnated with iron ion solution and oxidized to gain the magnetism, The process was simple and had a practical value. The experiment resultes showed that the property of activated carbon was influented weakly by heating rates, a high hardness activated carbon with iodine value 1010mg/g was obtained through carbonization to 900 ℃ and activated 110 mins at that tempreture. the adsorptivity of activted carbon was influented strongly by both of impregnant PH and iron electric-charge number. the adsorptivity was highest in neutral solution and lowest in basicity solution. Fe~(+3) could be absorbed more than Fe~(+2) for a same iron ion consistency. Activted carbon showed the same Au absobability in front and behind magnetism obtained. and absorbed the same amount Au as the market nonmagnetic activated carbon after 4.5 hours adsorption. The magnetism wasn t tost greatly after absorbing Au. |
