Adsorption Resins Apply

   Macroporous adsorption resin is type of intersectant polymer without ion exchange. It doesn’t dissolve in any acid, alkali, organic solvent and heated up because of intersectant solid structure. And make it high mechanical stabilization as its flexible structure, and high intersectant make it producing chemical. So when it is being in inclement condition, it has higher stabilization of physical and chemical property than gelable resin. The hot weightlessness temperature is 266℃. It has excellent heat-resistant and irradiate-resistant property, and its temperature is 150℃ or so for   polystyrene resin, it can endure 200℃-250℃ in short time. It mustn’t consider of inorganic salt, strong ion minimum-molecule compound for organic matter concentration. It has adsorption as FanDeHua gravitation and hydrogenolysis, and has filtration property as its multi holes structure and huge ratio surface, so it is a extraction material that is a compound adsorption and filtration property what is different from ion exchange resin. Its chemical structure has or hasn’t function radicel with different polarity.  It includes un-polarity, mid-polarity, polarity and strong polarity according to the surface property of resin.

Macroporous adsorption resin is widely used in environment protection﹑metallurgy industry﹑chemical industry﹑manufacture medicine﹑health department and etc, especially for biochemical products﹑natural products extraction and purification﹑medicines preparation﹑organic compound extraction﹑chemical reaction catalyzer﹑carrier and etc because of its own component and construction show the character of adsorption and sifting in extraction and purification.

        Macroporous adsorption resin is also widely used in the treatment of industrial waste water or waste liquid. It has very good effect in absorbing, recovery and purifying of benzene nitrobenzene﹑chlorobenzene ﹑fluorinbenzene ﹑phenol and so on organic compound. It has high adaptability to density of harmful ingredients in just one process. It makes it possible to recycle and repeat use the harmful substance in industrial production, and makes the harmful into useful and changes wastes into treasure.

      In recent years, macroporous adsorption resin is widely used in microorganism manufacture medicine in extraction and purification. New antibiotic published in overseas contain almost all kinds of compound with different composes, all that use macroporous adsorption resin as the way for active matter in extraction. Some antibiotic what belongs weak or non﹣ion exchange can’t be extracted in the way of ion exchange, but now macroporous adsorption resin can be tried to use for it. That can provide a new way for antibiotic in purification.

　 It is still the most active part for the reaction macromolecule technology field development. The practice show that it can provide stronger adsorbing ability ﹑easy rinse﹑high mechanical strength﹑strong pollution-resistance that natural adsorption. Especially that can control and choose man-made arbitrarily for the aperture﹑oppose surface area﹑polarity and so on. So it provide that very important way for microorganism manufacture medicine in extraction﹑concerntration﹑purification and so on, and make up the shortage of ion exchange instead of classic adsorption such as active charcoal and AL203 and etc.

Macroporous adsorption resin is widely used in medicine manufacturing and in extraction of active ingredients in natural plants such as glycosides, flavone , alkaloid etc. what belong to macromolecule chemical compound, it works well in the extraction of ginsenosides ,gypenosides,saponin on diosgenin,seviosides, liquorice P.E., Ginkgo Biloba leaf P.E., hawthorn leaves P.E., Astraglus extract, orange skin P.E., epimediosides,Pueraria Poot P.E. soybean biochanin, polyphenols , notoginsenosides, orange extract, yew P.E. various natural pigments, Chinese medicine compound. It also has very good result in the purification, separation, and recovery of biochemistry medicine making. It is also widely used in antibiotic , vitamin, amino acid, protein purification and biochemical medicine and etc.

The recommended condition of operation

Specific property and usage of macroporous adsorption resin

(1)    Water content of the resin is about 70%. It should be stored in a temperature over 0℃ in wet state. Avoid frozen breakage of ball body.

(2)    Its physical chemical property is stabled. It does not dissolve in acid, alkali and organic solvent, indissolubility, hot weightlessness temperature 266℃.

(3)    Before it is used the resin should be pre-treated accordingly depending on application purpose. That is to eliminate through infiltration the inertia solvent remains inside the resin holes. The pre-treatment method is to add as much ethanol as to a level 10cm above the resin layer in the extraction vessel and infiltrate 4hours before rinsed by ethanol. The rinse should be made to a extent that the flowed out liquid becomes non-cloudy when water diluted in test tube. Then wash it repeatedly by water to an extent that ethanol content less than 1% or there is no obvious ethanol smell. Then it can be used in productions. The medical grade resin of our factory has undergone deep treatment. So it can be used directly in productions.

(4)    In production, we suggest fill in 2 meters high of resin, and make adsorbing flow speed 4-10 meters/h (1-4BV/h), methanol, acetone can desorption.

(5)    Resin regenerate: after a period of using, the resin will become weak in its adsorbing ability and maybe contaminated. So it needs regenerate. The method is to add 3%-5% hydrochloric acid solution to a level 10cm above resin layer in the vessel and infiltrate for 2-4 hours, and then resin rinsed. Then use same density hydrochloric acid solution of the quantity 3-4 times that of resin to rinsed and then wash with clear water to an extent near neural. Then infiltrate with 3%-5% sodium hydroxide solution for 4 hours. Then rinse. Using same density sodium hydroxide solution of the quantity 3-4 times that of resin volume rinse. Finally wash with clear water approach to an extent that PH become neutral.
