重碳酸型地下水矿化度测定方法的探讨──以洛阳市浅层地下水为例

Approach on Determination of Degree of Mineralization for Bicarbonate Type Groundwater

矿化度是地下水化学成份测定的重要指标，在环境监测中，用重量法测定矿化度是目前普遍采用的方法。其缺点主要为费时，繁琐，耗电。本文通过测定洛阳市地下水的电导率，分析对比电导率与矿化度的关联，并进一步用回归方程确定电导率与矿化度之间的数量关系，探索出用电导率法间接测定地下水矿化度，具有快速，经济，准确的优点。

degree of mineralization is an important index in the groundwater analysis In environmental monitoring,the conventional method to determine the degree of mineralization for groundwater is weighting method Through determining the Luoyang groundwater conductivity,analyzing the relationships between conductivity and mineralization rate,and establishing the quantitative relations between conductivity and mineralization rate by using regression equations We find out the indirect method for determining mineralization rate by conductivity method The advantages for conductivity method are speedy,economical and accurate
