摘要
本文简要介绍了运用电位滴定法对水中Ca2+，Mg2+，Cl-及F-离子进行测定，利用化学计量点时电位的突跃来确定终点．方法简便、快速、灵敏、准确，符合定量分析要求，可用于环境监测之中．
The determination of Ca2+, Mg2 +, Cl-and F- ions in water by potentiometric titrationwas introduced the titration terminal was determined by potential in chemical equivalent. Themethod is simple, fast, sinsitive and accurate, which meets the requirement of quantitativeanalysis,and can be used for environment monitering.
