“…The exact peak potential became more negative as the charge density of the polymer increased. Previously such desorption peaks have been used to determine the concentration of various small surface-active species (6). The heights of the desorption peaks on our tensammograms were a function of the charge density of the pam used.…”

TRUIS SMITH-PALMER and BYRON R. WENTZELL. Can. J. Chem. 68, 26 (1990). The charge densities of acrylamide/acrylate copolymers can be determined using tensammetry. The tensammograms were run using 20 ppm solutions of polymer in 0.1 M tetraethylammonium chloride. A standard curve of desorption peak height versus mol% anionicity was useful in the range 10-50%. A second standard curve of the potential at which the capacitive current measured 1 pA versus mol% anionicity allowed the determination of charge density in the range 0-15%.

Tensammetric Analysis of Nonionic Surfactant Mixtures by Artificial Neural Network

An artificial neural network (ANN) model has been developed for tensammetric determination of a series of Brijes (Brij 30, Brij 35, Brij 56, Brij 96) as nonionic surfactants. The tensammetric method is based on the measurement of the capacitive current of the mercury electrode after adsorption of surfactants. All Brijes were analyzed in the concentration range of 1.0 -100.0 mg mL À1. The proposed method shows good sensitivity and applicability to the simultaneous determination of mixtures of four Brijes in aqueous solutions.
