APPLICATIONS OF A.C.OSCILLOPOLAROGRAPHIC TITRATION IN PHARMACEUTICAL ANALYSIS——Ⅱ. TITRATION OF DISODIUM DIMERCAPTOSUCCINATE WITH Cd

In NH₄OH—NH₄Cl buffer solution, disodium dimercaptosuccinate can be directly titrated with standard aqueous solution of CdI₂, using the disappearance of the incision of disodiurn dimercaptosuccinate as the end point. This method is simple and rapid and superior to the official method. The result of determination is in agreement with that of official method.
