Chronocoulometry as just described involves measurement of charge after what is frequently referred to as the forward potential step. A logical extension of the method is to step the potential to its original value or some other value Ef at which the redox process is reversed, and to monitor the resulting charge behavior (see Fig. 3.5) [13]. 

For decades the electrochemical techniques, i.e., potential, current, or charge step methods such as - chronoamperometry, - chronocoulometry, - chrono-potentiometry, coulostatic techniques were consid-... 

An improvement upon the chronocoulometric method described above represents the technique reported by Foresti et al. [218]. According to their procedure the potential-step chronocoulometry has been shown to provide all quantitative information about the adsorption of organic surfactants which may be completely desorbed at experimentally accessible negative potentials. 

For decades the electrochemical techniques, i.e., potential, current, or charge step methods such as chronoamperometry, -r chronocoulometry, chrono-potentiometry, coulostatic techniques were considered as fast techniques, and only with other pulse techniques such as temperature jump (T-jump) introduced by Eigen [i] or flash-photolysis method invented by Norrish and Porter [ii], much shorter time ranges became accessible. (For these achievements Eigen, Norrish, and Porter shared the 1964 Nobel Prize.) The advanced versions of flash-photolysis allow to study fast homogeneous reactions, even in the picosecond and femtosecond ranges [hi] (Zewail, A.H., Nobel Prize in Chemistry, 1999). Several other techniques have been elaborated for the study of rapid reactions, e.g., flow techniques (stopped-flow method), ultrasorhc methods, pressure jump, pH-jump, NMR methods.
