摘　　要：将磁化技术引入活性炭对重金属离子的吸附中,考察了预磁和吸附过程中加磁对铁离子、镍离子和铜离子活性炭吸附容量的影响。实验表明,经过磁化处理的活性炭对铁离子和镍离子的吸附容量下降,对铜离子的吸附容量增加。预磁的效果比吸附过程中加磁的效果要强,且随着磁场强度的增加,活性炭对重金属离子的吸附容量变化越大。The absorption of Fe3＋, Ni2＋ and Cu2＋ on activated carbon in magnetic field was investigated. Effect of premagnetization and magnetizing in the absorption process on adsorption capacity of activated carbon for Fe3＋, Ni2＋and Cu2＋ was analyzed. The results show that adsorption capacity of magnetized activated carbon for Fe3＋ and Ni2＋decrease, but its absorption capacity for Cu2＋ increases; meanwhile, effect of the premagnetization is stronger than magnetizing in the absorption process. The stronger the magnetic field intensity, the greater the absorption capacity change of activated carbon.
