Abstract:

研究电镀废水中金属离子Au2+,Ag+,Cu2+,Ni2+在褐藻(Laminaria japonica)上的生物吸附-解吸动力学.研究结果表明,Au2+,Ag+,Cu2+,Ni2+在藻粉上的生物吸附可以分为2个阶段.第1阶段为物理吸附,在10 min内快速达到平衡,其吸附过程可很好地用准二级动力学方程来描述,准二级速率常数(k2)分别为0.110 6,0.381 8,0.458 9,2.691 2 g.(mg.min)-1,平衡时吸附量(qe)分别为2.52,0.54,2.46,8.62 mg.g-1.Au2+,Ag+,Cu2+,Ni2+在藻粉上的生物解吸过程与吸附的过程相似,也可以很好地用准二级动力学方程来描述,其动力学参数(k2)分别为10.650 8,4.926 4,0.655 6,0.031 2 g.(mg.min)-1,吸附量(qe)分别为0.20,0.07,0.84,29.41 mg.g-1.Laminaria japonica可用于处理电镀废水和废水中贵重金属的回收.
