A method of conductometric titration for determination of methenamine is presented. An aqueous solution of silicotungstic acid is used as titrant. The acid and methenamine form an insoluble compound in which the molar ratio of the acid to methenamine is 1:4. Conductometric curves were obtained, the shapes of which are suitable for accurate and reproducible determination of the end point of titration. The results show reasonable accuracy. Good reproducibility was achieved even when small quantities of methenamine had to be determined.
提出了一种用于测定乌洛托品的电导滴定法。使用硅钨酸水溶液作为滴定剂。该酸与乌洛托品形成一种不溶性化合物，其中酸与乌洛托品的摩尔比为1:4。获得了电导曲线，其形状适用于准确且可重复地测定滴定终点。结果显示出合理的准确度。即使在必须测定少量乌洛托品时也实现了良好的重现性。
