,5-benzopiazselenol (NSD)formed by reaction of Se(IV) and 2,3-diaminonaphthalene(DAN) was ex-tracted with cyclohexane and then injected into an HPLC ODS column( 150mm × 5mm)with a moblie phaseof acetonitrile at a flow rate of 1.0mL/min and detected fluorimetrically. The selenium content in fish hasbeen determined by this method with good results and recoveries. The limit of detection was 0.1ng.
