| 摘 要： | 本文研究了柳江河沿岸土壤和沉积物对磷的吸附及解吸动力学。在实验条件下．柳江河沿岸土壤对磷吸附速度较快，吸附规律符合交换平衡动力学方程：t／Xd(t)=t／Xd(eq) B。在相同实验条件下，柳江河沉积物则出现了释磷现象。

| Abstract: | Adsorption kinetics of phosphorous on coastwise soil and desorption from sediment of Liujiang River were investigated. When pH value is 7 and original concentration of phosphorous is 2.0mg/l, the adsorption kinetics of phosphorous on soil can be well described by exchange equilibrium kinetics models:t/X d(t)=t/X d(eq) +B. At the same time, phosphorus from sediment was released. |
