Method for determining adsorption state of organic substance adsorbed on resin particle

摘要

PROBLEM TO BE SOLVED: To provide a method of determining the absorption state of organic substances absorbed by an ion exchange resin, and to provide a method of managing a water treatment system by grasping the state of contamination by traces of organic substances contained in raw water being treated using the method of determining the absorption state and managing a replacement schedule for the ion exchange resin.SOLUTION: A method of determining the absorption state of organic substances absorbed by resin particles involves; comminuting the resin particles with organic substances absorbed thereby; sweeping excitation wavelength and measuring intensities at fluorescence peaks of at least two excitation wavelengths using fluorometry; and predicting an amount of absorbed organic substances based on a ratio of two intensities. The absorbed amount thus predicted by using this method is used to determine a replacement schedule of the ion exchange resin for water treatment system management.SELECTED DRAWING: Figure 2
