After the extraction of gallium with diethyl ether, however, the conditions of the resultant gallium solution differed considerably from those recommended by Belcher et alas for the ferrocyanide titration. When known amounts of gallium were taken through such a procedure, the recoveries were always low owing to the difficulty of detecting the end-point of the titration. The titration conditions were therefore investigated. The influence of the pH value on the titration of 1.47 mg of gallium is shown in Fig. 4, the optimum pH range for complete recovery being from pH 2-2 to 2.5. Known amounts of gallium were next taken through the diethyl ether extraction procedure and the pH values of the resultant aqueous solutions were adjusted to the optimum pH range each time before the ferrocyanide titration.
