SILICA CONCENTRATION AUTOMATIC MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a compact and inexpensive silica concentration automatic measuring device for the continuous automatic measurement capable of easily and quickly measuring a silica component of low concentration with high accuracy, and measuring its absorbance by performing the color reaction on the silica component in the water to yellow color by a light source of long life. SOLUTION: A transmittance of the reaction solution prepared by color reaction of silica ion in the sample water and the ammonium molybdate dripping reagent solution by mixing the sample water and the ammonium molybdate dripping reagent solution, is automatically measured by an ultraviolet light- emitting diode having a peak wavelength in 370 nm-400 nm.
