AB-8
AB-8 macroporous adsorption resin is styrene type weak polar copolymer (crosslinking agent is divinylbenzene, monomer is methyl acrylate, porogen is toluene, etc.).It is suitable for the extraction, separation and purification of water-soluble and weakly polar substances, such as stevioside and alkaloids.
Product Features:
1. The color milky white or light yellow brings convenience to the processing operation, and the separation and purification of the colored organic compounds are easy to observe.
2. The physical and chemical properties are stable, and it is insoluble in any acid, alkali and organic solvent, which is convenient for the selection of adsorbent and desorbent.
3. It has good selectivity to organic matter and is not affected by the presence of inorganic salts.
4. The regeneration is easy. The regeneration agent can be selected from water, dilute alkali, dilute acid or low-boiling organic solvent. Such as: methanol, ethanol, acetone, etc.
5. Good mechanical strength and long normal service life.
Resin pretreatment
Industrial grade resins all have inert solvents, so they must be pretreated to different degrees according to the needs of the application: in the extractor, add 10-20 cm of ethanol above the resin layer to soak for 3-4 hours, and then drain the soaking solution , For an extraction process. Use the same method to wash repeatedly until the outlet takes the soaking solution and add 3 times the amount of water to the test tube until it is not turbid. Then rinse it thoroughly with clean water until there is no obvious smell of ethanol, then it can be used for general use.
V. Enhanced regeneration:
When the resin is normally used for a certain period, the adsorption capacity is reduced or it is acutely polluted, it is necessary to strengthen the regeneration treatment. The method is to add 3-5% hydrochloric acid solution 10-20 cm above the resin layer and soak it for 2-4 hours. The same concentration of 5-7 times the volume of hydrochloric acid solution was rinsed, and then rinsed thoroughly with clean water until the pH value of the outlet washing solution was neutral, and then soaked in 5% sodium hydroxide solution according to the above method for 2-4 hours, and used the same Method Rinse until 5-7 times the volume of sodium hydroxide solution is passed, then rinse thoroughly with water until the pH of the effluent is neutral, and then it can be put into use again.
Precautions
1. The resin contains water and should be kept at a temperature of 5-40ºC during storage and transportation to prevent freezing at low temperatures and mildew at high temperatures, which affects its use.
2. Because the resin is exposed to the air or loses water for any reason, do not directly inject water to prevent the resin from floating. It can be impregnated with ethanol to restore it to a wet state and then cleaned with water.
3. The adsorbed substance (solution) should be subjected to impurity removal, filtration, and clarification before being put on the column, so as to avoid impurities entering the resin column as far as possible, so as not to cause acute resin poisoning and affect the use.
4. Resin is interrupted. After washing with water, it should be stored in soaked clean water and changed regularly to prevent contamination. It can also be immersed in saturated saline or ethanol for long-term storage.
