Overview
Boiler water treatment resin 732 electric standard cation resin * r $n ion exchange resin contains a certain amount of moisture, which should be kept as much as possible during transportation and storage. If the resin loses water during storage, it should be soaked in concentrated saline water (8-10%) for 1-2 hours before gradually diluting. It should not be directly placed in water to avoid rapid expansion and breakage of the resin. During storage or transportation, the resin should be kept in a temperature environment of 5-40 ℃ to avoid overcooling or overheating, which may affect its quality. If there is no insulation equipment in winter, the resin can be stored in saline solution, and the temperature of the saline solution can be determined according to the temperature.

Pre treatment of Yang resin
The pretreatment steps for cation resin are as follows:
Firstly, use saturated saline solution, which is approximately twice the volume of the treated resin. Soak the resin in the saline solution for 18-20 hours, then drain the saline solution and rinse with clean water to ensure that the discharged water does not turn yellow; Next, use a 2% -4% NaOH solution with the same amount as above, soak in it for 2-4 hours (or perform a low flow cleaning), drain the alkaline solution, and rinse the resin until the discharged water is close to neutral. Afterwards, use a 5% HCl solution with the same amount as above, soak for 4-8 hours, drain the acid solution, and use a clear solutionDrift the water to neutral for later use.

Some macroporous resins without exchange functional groups can also adsorb and separate various substances, such as phenolic compounds in chemical plant wastewater.
NaOH， The concentration.
Acidic solution dissolves alum dental floss, turning it into Fe3, which may also cause iron contamination. Sodium ion exchange cation exchange resin, which is generally used for softening water treatment, is more susceptible to iron contamination. Iron contamination of anion exchange resin is mostly caused by Fe2O3 and sodium chloride contained in the regenerated caustic soda solution, which generate ferrates (such as Fe2O43). After entering the anion bed with the alkaline solution, ferrates and alkaline solution.
What are the regeneration methods for ion exchange resins? The regeneration of ion exchange resin is to restore its lost ion exchange capacity.
Due to the decrease in acidity and alkalinity compared to the previous period, a decomposition reaction occurred, and Fe3 further formed iron (hydroxyl) 3. Iron contamination was caused by the surface of the anion resin particles. 3. Identification method: Take a certain amount of resin contaminated with iron, wash it with clean water, soak it in a saline solution, regenerate for about half an hour, pour it out for consumption, and then wash it with distilled water 2 to 3 times. Take out a small part of the resin and put it into a stoppered test tube, add 6mol/L solution, add twice the volume of resin, cover it tightly and shake for 15 minutes, and take out a small part of the acidic solution into another test tube.
The commonly used regeneration methods include downstream regeneration and countercurrent regeneration.
