Application of CAS: 9002-29-3|AMBERLITE(R) IRC-50:
Used for pure water preparation, water softening, non-ferrous metal separation.

Note of CAS: 9002-29-3|AMBERLITE(R) IRC-50:

1. Ion exchange resin contains a certain amount of water and should not be stored in the open air. It should be kept moist during storage and transportation to avoid air drying and dehydration, which may cause the resin to break. If the resin is dehydrated during storage, it should be soaked in concentrated salt water (10%) first. Then gradually dilute it and do not put it directly into the water to prevent the resin from rapidly expanding and breaking.

2. During winter storage and transportation, it should be kept in a temperature environment of 5-40 degree to avoid overcooling or overheating, which will affect the quality. If there is no insulation equipment in winter, the resin can be stored in salt water. The concentration of salt water can be adjusted according to the temperature. Depends.

3. Industrial products of ion exchange resin often contain a small amount of low polymers and unreacted monomers, as well as inorganic impurities such as iron, lead, copper, etc. When the resin comes into contact with water, acid, alkali or other solutions, the above-mentioned Substances will be transferred into the solution and affect the quality of the effluent. Therefore, the new resin must be pretreated before use. Generally, the resin is fully expanded with water first, and then the inorganic impurities (mainly iron compounds) in it can be treated with 4-5 % dilute hydrochloric acid to remove, organic impurities can be removed with 2-4% dilute sodium hydroxide solution, wash until nearly neutral. If used in preparation, it must be soaked in ethanol.

4. When the resin is in use, avoid contact with metal (such as iron, copper, etc.) oil, organic molecular microorganisms, strong oxidants, etc., so as to avoid reducing the ion exchange capacity or even losing its function. Therefore, the resin must be inspected irregularly according to the situation. Activation treatment, the activation method can be determined according to the pollution situation and conditions. Generally, the cation resin is susceptible to Fe pollution during softening and can be soaked in hydrochloric acid, and then gradually diluted. The anion resin is susceptible to organic pollution, and 10% NaC1+2-5% NaOH can be used Soak or rinse in the mixed solution. If necessary, soak in 1% hydrogen peroxide solution for several minutes. In addition, acid-base alternating treatment, bleaching, alcohol treatment and various sterilization methods can also be used.

5. Pretreatment of new resin: Industrial products of ion exchange resin often contain a small amount of oligomers and unreacted monomers, as well as inorganic impurities such as iron, lead, and copper. When resin comes into contact with water, acid, alkali or other solutions, the above substances will be transferred into the solution, affecting the quality of the effluent. Therefore, new resin must be pre-treated before use. Generally, the resin is expanded with water first, and then the inorganic impurities (mainly iron compounds) can be removed with 4-5% dilute hydrochloric acid, and the organic impurities can be removed with 2-4% dilute sodium hydroxide solution and washed until they are nearly neutral. Can.
