NEW METHODS FOR THE DETERMINATION OF FREE ACID IN THE PRESENCE OF LARGE AMOUNTS OF URANYL SALT

Two new methods were developed for the determination of free acid in solutions containing large amounts of uranyl salt. Both methods are based on the weakening of the acidic properties of the uranyl ion, which is brought about by its bonding to sulfate ions. By utilizing this complex formation it is in fact possible to arrive at a titration curve of two distinct steps. According to the first method, the free acid is determined by potentiometric titration to the well determinable point of inflection between these steps. For low concentrations of acid, however, when a titration is not practical, the free acid is instead determined by direct measurement of pH, according to the second method described. (auth)
