| 摘 要： | 通过静态吸附试验和吸附热力学与吸附机理探讨,表明pH值和活性炭投加量是影响活性炭从水中吸附重金属的主要因素,吸附容量随pH值增大而增大,但却随着吸附剂投加量的增加而减少;吸附规律可用Freundlich模式和Lang muir模式很好的模拟,重金属的吸附能力大小是Fe3 + >Cu2 + >Ni2 +

| Abstract: | Through the discussion on the static test,the thermodynamics and mechanism of the adsorption,we can conclude that the pH value and adsorbent amount have important effect on the adsorption of the heavy metals in wastewater treatment,and the result can also be found that the adsorption capacities increase with the rise of the pH value,but decrease with the rise of the adsorbent amount,the law for adsorption can be described by Freundlichand Langmuir models and the sequence for the adsorption capacities is :Fe 3+ >Cu 2+ >Ni 2+ . |
