Abstract
|
|
|
|
Voltammetric analysis of Cl(I) ion was performed using a metal gold (Au) electrode (AE) and a carbon nanotube electrode (CNTE). After the examination, the AE was found to have more sensitively detected Cl(I) than CNTE. The optimum analytical conditions for the cyclic voltammetry (CV) and the square wave (SW) stripping voltammetry were performed using AE. The detection limit of 6.5 ㎍/ℓ Cl(I) was attained. The developed techniques were compared with the common Cl meter and applied to water systems.
