(57) [Problem] To easily and accurately evaluate the performance of an anion exchange resin packed and used in a mixed-bed type ion exchange tower of a condensate and desalination unit of a power plant, and determine its replacement time. . SOLUTION: A polystyrene sulfonic acid solution having a known concentration is passed through a column 2 packed with an anion exchange resin, and UV The UV absorptivity of the column effluent was measured with an absorptiometer 3, the polystyrene sulfonic acid concentration of the effluent was determined from the measured value, and the amount of polystyrene sulfonic acid adsorbed on the anion exchange resin was calculated from the result to obtain the anion exchange resin. Evaluate performance and remaining life. |
