Macroporous adsorption resin is a synthetic polymer adsorbent with porous stereo structure. It is a new type of resin developed on the basis of ion exchanger and other adsorbent applications. It relies on it and adsorbed molecules (adsorbed matter). Between Van der Waals gravitation, it works through its massive physical adsorption than the surface. In practical applications, some molecules similar to their skeleton structure, such as aromatic cyclic compounds, have a strong adsorption capacity.
Macroporous adsorption resins are widely used in the extraction and separation of macromolecular compounds such as saponins, flavonoids, lactones and alkaloids in pharmaceutical and natural plants. Ginsenosides, Panax notoginseng, Gynostemma, Diosgenin, Stevioside, Glycyrrhizin, Ginkgo flavonoids, Hawthorn flavonoids, Astragalus saponins, Hesperidin, Epimedium flavonoids, Soy isoflavones, Tea polyphenols It has good effects on the purification, separation and recovery of biochemical products, such as digitalis heart, ephedra essence, pomelo, hairy flavonoids, yew alkaloids, various natural pigments, Chinese medicine compound drug extraction, etc. And in the antibiotics, vitamins, amino acids, protein purification, biochemical pharmaceuticals have a wide range of applications.
The macroporous resin adsorption separation process is one of the technologies that have a great influence on the extraction process of Chinese medicine and drive the surface. The process is simple in operation, low in cost, and the resin can be used repeatedly, which is suitable for industrial production. Calculated by investing 3 tons of crude drugs per day, the investment in fixed assets will be increased by 150,000 yuan, and the annual energy consumption, auxiliary materials, packaging materials, storage and transportation costs will be at least one million. Therefore, it has a strong promotion and application value, and will promote the leap-forward progress of Chinese medicine extraction technology.
At the same time, macroporous adsorption resins have a wide range of applications for the treatment of industrial wastewater and waste liquids. Such as wastewater containing benzene, nitrobenzene, chlorobenzene, fluorobenzene, phenol, nitrophenol, aminophenol, bisphenol A, p-cresol, naphthol, aniline, o-phenylenediamine, p-phenylenediamine, salicin Organic substances such as acid, 2, 3 acid, and sodium sulfonic acid have good adsorption, recovery and purification effects. Moreover, it is highly adaptable to the concentration of harmful substances in the waste liquid, and can be used for one-time compliance. It can realize the purpose of recycling and reusing harmful substances in industrial production, turning harm into profits and turning waste into treasure.
Notes on application of ion exchange resin:
1) Storage and transportation
1 should be stored in a sealed container to avoid cold or explosion.
2 Storage temperature: between 4 ° C and 40 ° C.
3 Resin storage period is 2 years, more than 2 years re-qualification can be used. If the resin is found to be dehydrated, do not add water directly to the resin. Add a proper amount of concentrated brine to restore the resin to moisture.
2) Pretreatment
The resin must be pretreated as follows before running.
1 cation resin pretreatment
The cation resin pretreatment steps are as follows:
First use saturated brine, take about twice the volume of the resin to be treated, soak the resin in the salt solution for 18-20 hours, then drain the brine and rinse with water to make the discharged water without yellow. Secondly, use 2%-4% NaOH solution, the amount is the same as above, soak it for 2-4 hours (or small flow cleaning), after draining the alkali solution, rinse the resin until the discharged water is close to neutral; after Zui Use 5% HCl solution, the amount is the same as above, soak for 4-8 hours, let go of the acid solution, rinse with water to neutral for use.
2 Pretreatment of anion resin The * step in the pretreatment method is the same as the * step in the cation resin pretreatment method; then immersed in 5% HCl for 4-8 hours, then the acid is drained, and washed with water to neutral; After soaking for 4-8 hours with 2%-4% NaOH solution, drain the lye and wash with water until neutral.
3) Prevent resin contamination
There are several cases of resin pollution, one is organic matter and colloidal silicon in raw water; the other is heavy metal pollution; and the other is polymer cracking in long-term operation of the resin itself, causing the crushing or exchange capacity to decrease, so it is necessary to distinguish the cause of pollution poisoning. Different treatment.
