AB-8

The AB-8 type macroporous adsorption resin is a styrene-based weakly polar copolymer (crosslinking agent is divinylbenzene, monomer is methyl acrylate, pore-forming agent is toluene, etc.). It is suitable for the extraction, separation, and purification of water-soluble substances with weak polarity, such as steviol glycosides and alkaloids.

    3. Product Features :

      1. Milky white or light yellow color facilitates handling operations, making it easy to observe during separation and purification of colored organic compounds.

      2. Physicochemical properties are stable; insoluble in any acid, alkali, or organic solvents. , Convenient for selection of adsorbents and desorbents.

      3. Good selectivity for organic substances; not affected by the presence of inorganic salts.

      4. Easy regeneration; regenerants can be water, dilute alkali, dilute acid, or low boiling point organic solvents such as methanol, ethanol, acetone, etc.

      5. Good mechanical strength and long normal service life.

     

    4. Resin Pretreatment:

      Industrial grade resin contains residual inert solvents, so before use, different degrees of pretreatment are required according to application needs: add ethanol 10-20 cm above the resin layer in the extractor for soaking. 10-20 centimeters of ethanol soaking above the resin layer 3-4 hours, then drain the soaking liquid for the first extraction process. Repeat washing by the same method until the soaking liquid collected at the outlet, when mixed with several times the volume of water in a test tube, is clear without turbidity. Then rinse thoroughly with clean water until no obvious ethanol odor remains, then it can be used normally. After packing the resin column, backflush with water to expel gases in the resin to avoid gas blockage affecting adsorption. 3 Backflush with water to expel gases in the resin to avoid gas blockage affecting adsorption.

     

    5. Enhanced Regeneration:

      When the resin's adsorption capacity decreases after normal use for a certain period or is severely contaminated acutely, enhanced regeneration is needed. The method is to add 10-20 cm above the resin layer 10-20 centimeters of 3-5% hydrochloric acid solution soaking 2-4 hours, then rinse with the same concentration 5-7 times the volume of hydrochloric acid solution, then rinse thoroughly with clean water until the outlet wash solution's pH is neutral, then soak with sodium hydroxide solution by the above method for 5% hours, and rinse with the same method until rinsed with 2-4 times the volume of sodium hydroxide solution, then rinse thoroughly with water until the effluent's 5-7 pH pH is neutral, then it can be put back into use.

     

    6. Precautions:

      1. This resin contains moisture; storage and transportation should maintain a temperature of 5-40 º C to prevent freezing at low temperatures and mildew at high temperatures, which would affect use.

      2. Resin should not be directly injected with water if it is exposed to air or loses water for some reason, to avoid resin floating. It can be treated by soaking in ethanol to restore its wet state, then rinsed clean with water.

      3 Adsorbate ( Solution ) Before loading onto the column, impurities should be removed, and the solution should be filtered and clarified. , Avoid impurities entering the resin column as much as possible. , To prevent acute poisoning of the resin. , Affect usage.

      4. When resin use is interrupted, it should be washed clean with water, soaked and stored in clean water, and the water should be changed regularly to prevent contamination. It can also be soaked in saturated saline or ethanol for long-term storage.
