在工业水质监测中，需要随时测定水中ＨＣＯ－３的含量。常规的化学方法是通过测总碱度计算出ＨＣＯ－３的含量。而电位滴定法，电位突跃小，很难确定终点，误差大。现采用电导滴定法快速测定工业水中ＨＣＯ－３的含量，用ＨＣｌ作滴定剂，随着滴定剂滴入，水中电导率发生变化，通过测电导率值绘制滴定曲线，确定滴定终点，求出ＨＣＯ－３的含量。方法简单、快速、结果准确，精密度高，极易确定滴定终点。此法适合水质检验、环境监测和工业生产监控。
In the industrial water quality monitoring, the content of HCO-3 in the water needs to be measured at any time. The conventional chemical method is to calculate the content of HCO-3 by measuring the total alkalinity. The potentiometric titration, potential jump is small, it is difficult to determine the end, the error is large. Is the use of conductivity titration rapid determination of industrial water, the content of HCO-3, with HCl as titrant, with the dropping of titrant, water conductivity changes, by measuring the conductivity value of the titration curve to determine the titration endpoint, find the HCO -3 content. The method is simple, rapid, accurate, high precision, easy to determine the titration end point. This method is suitable for water quality inspection, environmental monitoring and industrial production monitoring.
