2、 Working principle

HD-GSG typeMicro silicate ion analyzerUsing the principle of photoelectric colorimetry for measurement. Under pH conditions of 1.1-1.3, soluble silicon in water reacts with ammonium molybdate to form a yellow silicon molybdenum complex. The silicon molybdenum complex is reduced to silicon molybdenum blue using ferrous ammonium sulfate solution, and its silicon content is measured using a silicate analyzer. According to Lambert Beer's law, when a monochromatic parallel light passes through a colored solution, a portion of the light energy is absorbed by the solution. If the thickness of the liquid layer remains constant, the degree of light energy absorption (absorbance A) is proportional to the concentration of colored substances in the solution.
