| Abstract: | The present study introduced the experiment method of determining NH4-N in seawater by flow injection and spectrophotometric method.Through the conditional experiment and optimization,the best condition of the determination was given.Methods detection limit was 0.002 9 mg/L and the RSD ranged from 0.88% to 5.79%.The relative standard deviation of the method was 88.0%-101.0%.This method has some advantages such as fast,time-saving,convenient,little interference and better precision.Moreover,it is fit for assaying mass samples. |
