A laser-induced fluorometric method for the rapid determination of trace level? of uranium in seawater with the Modified Anti-interference Fluorometric Reagent for uranium (MAFG) is described. Only a sample volume of 1.5-2.5 ml is used in each determination and no pre-scparation and concentration steps are required. The analysis rate is a sample per 5 min. The relative standard deviation of ten replicate determinations on 3.44 ppb U of the natural seawater is 4.7%.
