Experiment on Dynamic Release of Fluorine from Sediment in Yangshapao Reservoir of Western Jilin Province

The specific studies are carried out according to the problem of the high concentration of fluorine in Yangshapao Lake, which is a most important multi-purpose reservoir of Diversion Project from Nenjiang River to Baicheng City in Western Jilin Province. After the diversion is actualized, the release of fluorine from the sediment may influence the water quality in the reservoir. Based on the problem mentioned above, dynamic release experiment is adopted to analyze the release concentration of fluorine changing with time, which found out that the release law of fluorine in sediment is according with logarithm distribution. The dynamic release equation and chemical reaction rate equation of fluorine in sediment are also established.
