氟在水土界面迁移转化的实验研究

Experimental study of transport and transformation of fluorine at water-soil interface

本文以吉林西部乾安县境内湖泡作为研究对象,通过氟的解吸实验对影响水土界面氟迁移转化的因素进行研究,运用水环境化学、水文地球化学、土壤化学等多学科综合方法对氟在水土界面的迁移转化机理进行分析,结果表明底泥释放到上覆水体中可溶性氟的量与温度、钙钠吸附比、浸泡液的pH密切相关。

Taking the lakes in Qian'an county in west Jilin province as research objects,the paper studies the influence factors of the transport and transformation of fluorine at the water-soil interface through the desorption experiment of fluorine,analyzes the transport and transformation mechanism by the synthesis comprehensive methods,including water environmental chemistry,hydro geochemistry,soil chemistry,etc.The result shows the quantity released of fluorine from sediment to the overlying water is closely related to temperature,adsorption ratio of calcium and sodium and the PH of the soak.
