Title:
METHOD FOR MEASURING SILICA FORM IN WATER
Document Type and Number:
Japanese Patent JP2021181903
Kind Code:
A
Abstract:
To provide a method for measuring a silica form in water, which can quickly and easily measure molecular size distribution of silica in water.SOLUTION: After a liquid feed pump 3 supplies sample water to a sample water chamber of a flat membrane cell unit 10, high-pressure air from a high-pressure compressor pressurizes the inside of the sample water chamber, filtrate is taken out, and silica concentration in the filtrate is measured. This measurement is performed using a plurality of membranes having different molecular weight cut-off, and silica molecular weight and/or particle size distribution are estimated.SELECTED DRAWING: Figure 1
