  • Title: The determination of aluminium in antacid formulations by Gran's Plot titration with sodium fluoride.
    Author: Cooper ME, Ballantine J, Woolfson AD.
    Journal: J Pharm Pharmacol; 1979 Jun; 31(6):403-5. PubMed ID: 39142.
    Abstract:
    The aluminium content of a number of proprietary antacid formulations has been determined by titration with sodium fluoride, using the fluoride activity electrode as an end-point detector. Results compared favourably with the official method. The fluoride titration, however, involved less sample manipulation and was more rapid to carry out. End-point detection was made easier by treating titration data by the Gran's Plot method.
