研究了Cu(II) 在泉州湾滩涂沉积物上的吸附行为。探讨了pH和温度对吸附作用的影响,测定了其吸附等温线。实验结果表明,常温下Cu(II) 在泉州湾滩涂沉积物上的吸附平衡时间约需3.5 小时;吸附量随pH的升高先增大而后减少,pH=6.0左右时达最大;吸附量随温度的升高而增大;其吸附行为可以很好地用Langmuir型吸附等温线来描述。并在此基础上初步探讨了Cu(II)在泉州湾滩涂沉积物上的吸附机理。
The adsorption behavior of Cu (II) on the sediments in the beach of Quanzhou Bay was studied. The effect of pH and temperature on the adsorption was discussed. The adsorption isotherm was measured. The experimental results show that the adsorption equilibrium time of Cu (II) in the sediment of Quanzhou Bay at room temperature is about 3.5 hours. The adsorption capacity first increases and then decreases with the increase of pH, and reaches the maximum at pH = 6.0. The adsorption capacity increases with the increase of temperature Increase and increase; its adsorption behavior can be well described by Langmuir adsorption isotherm. On this basis, the adsorption mechanism of Cu (II) on the sediments in Quanzhou Bay was discussed.
