Uncertainty Evaluation of the Determination of Active Silicate in Seawater by Silicon Molybdenum Blue Method
According to the Code of practice for marine monitoring technology,Part 1:seawater(HY/T 147.1-2013),active silicate in seawater was determined.Analyzing the sources of uncertainty,the uncertainty components were calculated and then the combined uncertainty and expanded uncertainty were calculated.The results show that the uncertainty of the deter-mination of active silicate in seawater mainly comes from the standard solution and the fitted standard curve.Through the evaluation of uncertainty,it was helpful to improve the reliability of the test results.
