Summary:
The adsorption behavior of strongly acidic cation exchange resin on ammonia nitrogen in high concentration coking wastewater was systematically investigated. The experimental results show that under static conditions, the adsorption capacity of resin to ammonia nitrogen in coking wastewater is 13.3 mg/g resin, and the maximum adsorption rate of ammonia nitrogen is 90.87%. Under dynamic experimental conditions, when the wastewater flow rate is 0.139~1.667 mL/s and the adsorption rate of ammonia nitrogen is greater than 97%, the maximum adsorption capacity of resin to ammonia nitrogen is greater than 2.5 mg/g resin. The failed resin can be continuously used after being regenerated with 0.5 mol/L dilute sulfuric acid. Under the conditions of this article, the resin has been regenerated for 10 times without any change in performance.

Summary:
this study found the synthesis method of macroporous crosslinked polystyrene ion exchange resin, and studied the relationship between the properties of inert solvent and the pore structure of resin, the pore structure of resin and the properties of resin, the properties and uses of resin, etc. On this basis, a macroporous ion exchange resin with high strength, radiation resistance and superior kinetic performance has been developed, which not only can be better applied to the exchange of inorganic ions, but also develops a wide range of applications in the fields of organic synthesis, pharmaceuticals, such as catalysis, decolorization, purification, etc. Based on porous ion exchange resins, a series of adsorption resins have also been developed. Such extraction and separation materials can have different structures and different adsorption properties, and have practical applications in the fields of extraction and separation of natural products, extraction and purification of antibiotics, medical treatment, environmental protection, etc. The above two types of functional polymer materials have been industrialized in many companies, providing necessary materials for many industries such as chemical, pharmaceutical, environmental protection, medical, and analysis, and playing an important role in the development of the national economy.

Summary:
A variety of macroporous strong acid ion exchange resins are selected to adsorb and concentrate copper ions in organic wastewater. By measuring the removal rate of copper ions by various resins, the effect of different copper ion concentrations and solution p H values on the removal rate, as well as the comparison of the regeneration performance of each resin, it shows that "glory","strong acid No, can be used for adsorption treatment of copper ions in organic wastewater.
