摘要
水溶液的电导率和溶解性总固体存在相关关系,在对水质检测数据进行质量审核以及野外现场水质监测时,可以通过电导率来快速估算水溶液的溶解性总固体。为探求西藏饮用天然水电导率与溶解性总固体的相关性,通过对数据的相关性分析,两者皮尔逊相关系数为0.983,具有极强的正相关性。回归分析结果显示,电导率与溶解性总固体成线性正相关关系,两者比值约为0.863,对电导率影响从大到小的主要离子为:碳酸氢根>Ca>Mg>硫酸根>Na>氯离子>K>碳酸根。
There is a correlation between total dissolved solids and electrical conductivity of aqueous solution.In the quality audit of water quality test data and field water quality monitoring,the total dissolved solids of aqueous solution can be quickly estimated by electrical conductivity.In order to explore the correlation between electrical conductivity and total dissolved solids of natural water in Tibet,through the correlation analysis of the data,the Pearson correlation coefficient was 0.983,with a strong positive correlation.Regression analysis showed that there was a linear positive correlation between the electrical conductivity and total dissolved solids,and the ratio was about 0.863.The main ions affecting the conductivity from large to small were:bicarbonate>calcium>magnesium>sulfate>sodium>chloride>potassium>carbonate.
