چکیده

Amperometric detection of nitric oxide with ISO-NOPMC NO microsensors (WPI) is systemically studied in the six media including seawater. The linear range of the microsensor for NO was from 10 to 10 mol/l and the detection limit was 4.2×10 mol/L(S/N=2). With this method, we provide preliminary evidence that NO production could be a general attribute of marine alga (Haeterosigma akashiwo). Experiment conducted with inhibitor of uncoupler 2,4-DNP (2,4-dinitropheno) revealed that NR (nitrate reductase) activity is responsible for NO formation.

The Electrochemical Detremination of Nitric Oxide in Seawater Media with Microelectrodes

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 1×10-1.2×10 mol/l for both microelectrodes. The detection limit of ISO-NOPMC microse...
