[0002] In wastewater sampling systems for water treatment, water quality monitoring resins play a crucial role. These resins are primarily used to remove impurity ions from water, achieving water purification. However, with prolonged use, hydrogen ion exchange resins gradually lose their adsorption, ion exchange, and desalination capabilities. This not only affects the efficiency and effectiveness of the water treatment system but also imposes an additional environmental burden.
