“…Very good agreement between this electrochemical method and the standard MBAS method was achieved in biodegradability tests of linear alkylbenzenesulfonate (LAS) and tetrapropylene alkylbenzenesulfonate (TBS). Nonionic surfactants have already been studied by different electroanalytical techniques, for example, by tensametry (4,12), by measuring polarographic maxima of oxygen (5,13) and of mercury (14), and by the Kalousek commutator technique (6,14).…”

The biodegradation of different types of nonionic surfactants was studied by the electrochemical method based on the measurement of adsorption effects at the mercury electrode and by the modified Wickbold method. The proposed electrochemical method is simple and rapid and applicable to direct determination of the loss of surfactant activity in the biodegradation testing. The biodegradation degree of nonionic surfactants obtained by the electrochemical method is lower than by the Wickbold method because the latter method does not determine some surface-active intermediates of biodegradation.

The following tensammetric schemes, alternating current (ac) polarography of fundamental harmonic and second harmonic, phase-sensitive ac, square wave tensammetry, differential pulse and normal pulse tensammetry, Kalousek commutator technique, derivative chronopotentiometry, and several other techniques, are reviewed. Thermodynamic background and kinetic limitations of tensammetric analytical signals are discussed. Special attention is given to the behavior of mixtures and to the consequences of association of the analyte as well as to applications of different tensammetric techniques.
