摘要
溶解性总固体测定的影响因素包括环境和操作个体。通常称量中平行性与稳定性不太容易掌控。而电导率的检测相对方便快捷,也有较好的重现性和稳定性。若二者存有较为显著的相关性,可通过测定电导率,来推算溶解性总固体的含量。本实验经分析比对得出自来水中溶解性总固体与电导率间存有较为显著的线性关系,r值为0.999。
Factors influencing the determination of total dissolved solids include environmental and operational individuals.Parallelism and stability in weighing are usually not easy to control.The detection of conductivity is relatively convenient and fast,and also has good reproducibility and stability.If there is a significant correlation between the two,the total dissolved solids can be estimated by measuring the conductivity.In this experiment,the comparative analysis showed that there is a significant linear relationship between the total dissolved solids in the tap water and the conductivity,and the r value is 0.999.
