百口泉地下水电导率与溶解性总固体相关性讨论

由于溶解性总固体的测定较为复杂,平行性、稳定性差,而电导率的测定简便、迅速,重现性、稳定性好,若二者相关关系显著,可通过测定电导率,按一定的比例推算水中溶解性总固体的量。通过对百口泉地下水的溶解性总固体与电导率的相关性的监测、分析,经统计检验,线性关系显著,其比值范围在065～076,均值为07,即百口泉地下水的电导率1μs/cm相当于070mg/L的溶解性总固体。

Discussion on the Relativity of Groundwater Conductivity and Total Dissolved Solids in Baikouquan

Total dissolved solid determination is complicated, badly replicable and stable But conductivity determination is fast, easy and has a good replicability and stability So it is possible to calculate total dissolved solid by determining conductivity if obvious relativity exists in both determination results This article studies and analyzes the relativity of groundwater conductivity and its total dissolved solid Statistical result shows that the relativity is clear The ratio range is about 0 65～0 76, average ratio is 0 7, i e 1μs/cm groundwater conductivity in Baikouquan is equal to 0 70mg/L total dissolved solid
