Abstract
A highly dispersed ultramicro palladium-particle modified carbon fiber microdisk array electrode (Pd-CFE) was employed for capillary electro phoresis-electrochemical (CEEC) detection of hydroxylamine (HA). The P d particles obtained were in the nanometer scale, had a high electroca talytic activity towards HA and exhibited good reproducibility and sta bility. A linear relationship between the current and the analyte conc entration was found between 5 x 10(-6) and 1 x 10(-3) mol/l of HA with a correlation coefficient of 0.9992. The detection limit was 5 x 10(- 8) mol/l. The applicability of the method for the determination of HA in river water and waste water was investigated.
