摘要
高氟地下水的水化学相关特征主要是氟与钙的相关关系。本文主要根据贵州含氟地下水的氟—钙正相关的水化学相关特征,结合我国北方一些高氟地下水的氟-钙相关特征,进行对比分析,探讨解释了我国北方高氟环境区地下水氟—钙负相关、氟—钙不相关和贵州含氟地下水氟-钙正相关等特征在水化学上的本质原因。
Hydrochemical correlativity of F-rich groundwaters is mainly F--Ca2+ correlation. On the basis of positive correlation of F--Ca2+ in the groundwtaers of Guizhou and comparison with some F--rich groundwaters in the north of China, the genesis of negative correlation and non-correlation of F--Ca2+ in the groundwaters in the north of China and positive correlation of F--Ca2+ in the groundwaters of Guizhou are probed. The results indicate that the positive correlation of F--Ca2+ of the groundwaters in carbonate rocks in Guizhou is mainly related to material sources of F-and Ca2+. Because contents of F-and Ca2+ do not come up to solubility of CaF2, negtive correlation of F--Ca2+ as same ion effect does not show in the groundwaters.
