Abstract
A method for the gravimetric determination of aluminum in pharmaceutical preparations is given. The method is dependent upon the gradual evolution of ammonia from urea in boiling acid solution containing succinic acid. Aluminum is quantitatively precipitated as the basic succinate which is filtered off and ignited to Al2O3. This method offers advantages over the conventional hydroxide method in that the precipitate obtained is dense, granular, and easily and rapidly filtered. The maximum pH obtainable is 4.6, thereby eliminating the possibility of excess alkalinity. Data are given which indicate that the succinate method gives more accurate and uniform results than the hydroxide method.
