| Abstract: | The method of rFIA- crystal violet- molybdophosphate was used to determine the phosphate in seawater. The optimum conditions were determined, and the salinity effect was solved efficiently. The obtained results showed the method had high sensitivity, precision and recovery efficiency, and was simple and quick, which was applicable to the in-situ autonomous monitoring technology. |
