柳江河沉积物去除水中Cu(Ⅱ)的实验研究

Studies on Adsorption of Sediment from Liujiang River for Cu^(2+)

通过对柳江河沉积物与铜离子交换吸附作用的实验研究发现 :1 )铜离子与沉积物的交换吸附为一价阳离子交换 ;2 )不同站位的沉积物对铜离子的交换吸附能力不同 ;3 )吸附规律符合 Freundlich和

Exchange adsorption properties of the sediment from Liujiang River for Cu 2+ were studied. The results are as follows:(1)Exchange adsorption of the sediment from Liujiang River for Cu 2+ at each station is exchange reaction of cation. (2) Exchange adsorption abilities of the sediment for Cu 2+ vary greatly with different stations.(3) The adsorption isotherms of sediment for Cu 2+ conform to Freundlich adsorption equation and Langmuir adsorption equation.
