Abstract

A square-wave voltammetric method for the determination of boric acid in water has been described based on the new understanding of the electrochemical behavior of boric acid-Azomethine H complexation. Salicylaldehyde and H-acid were used as the starting materials of boric acid-Azomethine H complex and their concentrations were optimized for boric acid determination in water. A glassy carbon electrode, instead of a conventional mercury electrode, was used in the measurement. The detection limit of the proposed method was 0.10mgBdm-3. The proposed method was successfully used for boric acid determination in the water from a seawater desalination RO plant.
