The determination of aluminium in antacid formulations by Gran's Plot titration with sodium fluoride.
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.
