摘要
提出了用碘作滴定剂的电位滴定新方法。灵敏度高于２，６－二氯靛酚电位滴定法。实测了几种蔬菜样品，变异系数为２．７％～３．０％，回收率为９９．３％～１０１．５％。
A new method for potentiometer titration using iodium as titrant is put forward.It is more sensitive than 2,6-diohloroindophenol potentiometer titration.Samples of several vegetables are determined.Coefficient of variation is 2.7%～3.0%;recovery,99.3%～101.5%.
