Abstract

The electrochemical determination of nitric oxide in seawater with microelectrodes is reported in this paper. Two electrodes, ISO-NOPMC microsensor and modified platinum microelectrode, are evaluated for their performance in seawater. The peak current is found to be linear with the NO concentration in the range 1×10-6-1.2×10-5 mol/l for both microelectrodes. The detection limit of ISO-NOPMC microsensor is 1.4×10-8 mol/l. Two methods for calibration of NO sensor, saturated NO solutions and decomposition of S-nitroso-acetyl-DL-penicillamine (SNAP), are discussed and compared. In addition, we examined the performance degradation of these microelectrodes in seawater due to complexation with seawater components.
