孝感市澴河沉积物对Ca的吸附特征研究

Study On The Adsorption Characterists Of Calcium Of Xiaogan Huan River

本文对钙在环河的分布及钙的吸附-解析能力做了初步研究,结果表明:沉积物中有机物的含量越高,阳离子交换量的值越大,但钙的含量与OM、CEC并不是正相关,钙在沉积物中的形态有待进一步研究。通过对沉积物加去离子水震荡离心测钙含量的研究表明钙易从沉积物中析出,且达到一定值后,便很难继续析出了。

We have a preliminary study on the distribution of Calcium in Huan River and the ability of Calcium＇s adsorption in this paper.The result shows that,the higher the organic matter（OM） of the sediment,the greater value of the cation exchange capacity （CEC）,but the Calcium content is not positively related to the OM and CEC.We conclude from the oscillation of deionized water and sediment that the Calcium is easy to precipitate from the sediment until a certain value.
