| Abstract: | In order to meet the demand of auto-analyzing technology for silicate in seawater, Ascorbic acid was chosen as the reducing agent to measure the silicate and the analytical method was optimized. The relation between the light absorption value and the solution concentration, the reaction time were studied, and the salinity effect was determined. The authors also draw the chemical analysis technique optimization flow chart of seawater silicate in-situ autonomous monitoring technology. The analytical method was applied to the in-situ underwater analyzer, it can work for 43 days continuously, and the results have good reproducibility. |
