摘　　要：采用未改性的和氨化处理后的活性炭进行Cu2+的吸附平衡实验。考察了溶液p H、吸附温度对两种活性炭的吸附性能的影响。分别采用伪一次方动力学方程、伪二次方动力学方程考察了活性炭的吸附动力学行为。结果表明:经过氨化处理的活性炭能显著提高活性炭对Cu2+的吸附性能,这可能是由于活性炭表面的含氮官能团提高了活性炭的碱性造成的。The activated carbon and aminated carbon were used to adsorption of Cu^2＋. The effect of solution pH and temperature were investigated. The pseudo-first-order model and pseudo-second-order model were applied to study the adsorption kinetic of pristine and aminated carbon. The results indicated amination improved the adsorption capacity of activated carbon for Cu^2＋. The enhance adsorption capacity probably related to the nitrogen-containing groups on AC surface.
