摘要
通过岩土孔隙溶液成分、岩土及含氟矿物的淋溶、浸泡实验和土柱试验,揭示了河北平原第四系水土中氟的地球化学特征;并用Phreeqe软件对6种水-岩相互作用系统中氟的水文地球化学进行了模拟。
Fluorine is an essential element to human body,but excessive extraction will cause F-poisoning.The groundwater with high fluorine concentration covers a large area of Hebei Plain.By the laboratoy studies of the leaching and dissolution processes of fluorite in epigenetic situation by the thermodynamic equilibrium calculation of solubilities and finally by using Phreeqe software to simulate 6 systems of water-F-bearing minerals interaction,the problems concrning with the relationship between the behavior of the F-bearing minerals and the concentration of fluorine in groundwater are discussed. The results of these studies show a good agreement with the distribution of high F content groudwater in Hebei Plain.
