即使在滴定分析已被更新的方法所取代的时候，铋离子的络合滴定仍然是分析的选择。需要在硝酸存在下测定铋（III）离子并测定某些体系中的硝酸浓度。例如，在几种抗真菌制剂（1）的生产过程中，铋（III）与硝酸同时出现。以下滴定系统的重要性在于它允许两种物质的串联测定。
Complexometric titration of bismuth ion has remained the assay of choice even in a time when titrimetric analysis has been supplanted by newer methods. A need exists to assay for bismuth (III) ion in the presence of nitric acid and to determine the nitric acid concentration in some systems. During the manufacturing of several antidiarrheal formulations (1), for example, bismuth (III) appears concomitantly with nitric acid. The importance of the following titrimetric system is that it allows the tandem determination of both species.
