| 摘 要： | 本文研究了九龙江西溪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,沿岸土壤对磷有一定的吸附作用,其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,沉积物则出现了释磷现象。

| Abstract: | Adsorption kinetics of phosphorous on coastwise soil and desorption from sediment of xixi branch of Jiulongjiang River were investigated.When the 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/ Xd (t) = t/ Xd (eq) B.At the same conditions,phosphorus was released from sediment. |
