1. Ion exchange resin contains a certain amount of moisture and should not be stored outdoors. During storage and transportation, it should be kept moist 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 saline water (10%) first and gradually diluted. It should not be directly placed in water to avoid rapid swelling and breakage of the resin.

2. In winter storage and transportation, it is necessary to maintain a temperature environment of 5-40 ℃ to avoid overcooling or overheating, which may affect quality. If there is no insulation equipment in winter, the resin can be stored in salt water, and the concentration of salt water can be determined according to the temperature.

3. In industrial products of ion exchange resins, there are often a few low polymers and monomers that have not participated in the reaction, 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 substances will be transferred into the solution, affecting the quality of the effluent. Therefore, it is necessary to pre treat the new resin before use. Generally, water is used to make the resin fully swollen. Then, the inorganic impurities (mainly iron compounds) in between can be removed with 4-5% dilute hydrochloric acid, and the organic impurities can be removed with 2-4% dilute * solution, washed to near neutrality. If used in pharmaceutical preparation, it must be soaked in ethanol for treatment.

4. In the application of resins, it is necessary to avoid contact with metal (such as iron, copper, etc.) oil stains, organic molecular microorganisms, strong oxidants, etc., in order to prevent ion exchange from decreasing or even losing function. Therefore, the resin needs to be activated irregularly according to the situation. The activation method can be determined according to the pollution situation and conditions. Generally, cation resins are prone to Fe pollution during softening and can be soaked in hydrochloric acid and gradually diluted. Anion resins are prone to organic pollution and can be soaked or rinsed in a mixed solution of 10% NaCl+2-5% NaOH. If necessary, 1% hydrogen peroxide solution can be soaked for a few minutes. Other methods can also be used, such as acid-base replacement treatment, bleaching treatment, alcohol treatment, and various other methods.

5. Pre treatment of new resins: Industrial products of ion exchange resins often contain a small number of oligomers and monomers that have not participated in the reaction, as well as inorganic impurities such as iron, lead, and copper. When resin comes into contact with water, acid, alkali, or other solutions, these substances will transfer into the solution, affecting the quality of the effluent. Therefore, it is necessary to pre treat the new resin before use. Generally, the resin is first swollen with water, and then the inorganic impurities (mainly iron compounds) in between can be removed with 4-5% dilute hydrochloric acid. Organic impurities can be removed with 2-4% dilute * solution and washed until near neutrality.

The purification method of graphene oxide includes the following steps: ion exchange purification: sequentially passing the graphene oxide solution through cation exchange resin and anion exchange resin; The cation exchange resin is a hydrogen type cation exchange resin, and the anion exchange resin is a hydroxide type anion exchange resin. The purification method provided by the present invention has the advantages of simple operation and high purification efficiency. The content of each metal impurity in the purified graphene oxide is less than 10ppm; In addition, the used ion exchange resin can be reused through regeneration, which is energy-saving and environmentally friendly.
