天然矿泉水溶解性总固体与电导率的相关性探讨

摘要

The amount of total dissolved solids in the natural mineral water was calculated through detected conductivity. If the relativity of the two parameters was remarkable,the detection of total dissolved solids could be replaced because it was more complex and had a bad parallelism and stability. The detection of conductivity was easy, fast,and repeatable,and the stability was satisfied. The relativity discussion results of total dissolved solids and conductivity for source water in Laoshan mineral water indicated that a linear relation was obvious and the ratio was 0.84.%溶解性总固体的测定受环境和人为操作影响较大，平行性、稳定性差，而电导率的检测既方便又快捷，重现性、稳定性好，若二者相关性关系显著，可通过测定电导率，按一定的比例推算天然矿泉水中溶解性总固体的含量。经监控、分析崂山矿泉水的源水，二者线性关系较为显著，其比值为0.84。
