title: A potentiometric technique for kinetic determination of citrate, based on inhibition of crystalline growth of lead carbonate seed crystals.
abstract: The growth of lead carbonate seed crystals is strongly inhibited by the presence of citric acid. The kinetics of crystal growth were followed potentiometrically with a lead ion-selective electrode. The study of different variables on such a process was carried out with the aim of developing kinetic procedures to determine citrate (0.5-2.0 mug/ml). The selectivity and sensitivity of these processes allow the application of his crystallization reaction to direct determination of citrate in drinks and in a pharmaceutical product.
