Estimating the term…
The invention relates to a method for detecting the presence of boron in water comprising the production of a conductive buffer solution comprising water and at least one boron complexing agent, the introduction into an electrochemical cell of said solution in the presence of at least one work electrode (7), and the measurement of an anodic peak of the boron complex and complexing agent by voltammetry, said method being characterized in that the work electrode (7) is a solid microelectrode, and in that the measurement is carried out continuously with respect to the flow of water. The invention also relates to a device (10) for the implementation of such a method.
