摘  要:
选取我国北方典型碱性湖泊查干湖的沉积物为研究对象,在实验室运用水静态模拟方法研究了对于磷含量不同沉积物,在不同解吸时间(t)和不同水土比(W)条件下的解吸动力学过程。结果表明,在一定水土比条件下,沉积物中磷的释放量与解吸时间呈指数关系;在一定的解吸时间条件下,磷的解吸与水土比也呈现指数关系;而在一定的解吸时间和水土比条件下,磷的解析量与沉积物中磷的本底值成正比。通过实验,建立一个简单的解吸动力学模型Pd=0.017P0t0.875 W1.498,可以用来描述低温条件下查干湖沉积物中磷的解吸过程。

摘  要:
Research on the sediment of Chagan Lake,one of the typical alkaline lakes in northern China.Using water static simulation method in the laboratory to study the desorption kinetics with the content of phosphorus,desorption time(t)and water/soil ratios(W).The results showed that Preleased was exponentially related to t at any given W,and to W at any given t.The amount of Preleased was directly proportional to the value of the background in the conditions of some t and W.Through experiments,a simple desorption kinetics model could be created,as Pd=0.017P0t0.875 W1.498,which be used to describe the process of phosphorus desorption in Chagan Lake sediment at low temperature.
