A recording potentiometric/spectrophotometric titrator
Analytical Biochemistry, 1967A system for the simultaneous recording of spectrophotometric and potentiometric titrations at constant temperature is described. Application to the determination of the pK′ of the ionization of the iron-bound water molecule in horse and in sperm whale ferrimyoglobin and to the study of the attachment of nickel mesoporphyrin to human apohemoglobin A is

Linear potentiometric titrations
Journal of Electroanalytical Chemistry (1959), 1964Abstract A method for graphical representation of potentiometric titration curves is proposed. It permits determination of the end-point even if the conventional potentiometric curve, pH-volume, fails to define exactly an inflection point. The limits and the possibilities of the method are discussed and some examples of practical applications are ...

Potentiometric titration of viscose
Journal of Polymer Science, 1948AbstractA new method is investigated to determine by means of potentiometric titration the degree of ripening of viscose. It is found that when the e.m.f. of a characteristic inflection in the potentiometric titration curve is plotted against a measure of the degree of viscose ripening a sharp minimum occurs at a point corresponding to the optimal ...

Potentiometric titration of plutonium
Journal of Radioanalytical Chemistry, 1978In the potentiometric titration of plutonium(III), it has been customary to take the equivalence point as the inflection point on a plot of potential vs. volume of titrant.1 That the stoichiometric end point corresponds to the inflection point does not seem to have been theoretically demonstrated, however.

Potentiometric Titration of Metal Ions in Ethanol
Inorganic Chemistry, 2006The potentiometric titrations of Zn2+, Cu2+ and 12 Ln3+ metal ions were obtained in ethanol to determine the titration constants (defined as the at which the [-OEt]/[Mx+]t ratios are 0.5, 1.5, and 2.5) and in two cases (La3+ and Zn2+) a complete speciation diagram.
