Elution®eneration

Image
When the chromatographic medium is exhausted, it should be eluted. The basic principle is to desorb the target product by a more active ion or group. Different sorbents are different in their activity. Therefore, a suitable eluent should be selected to elute the protein from chromatography media. There are roughly three ways to stepwise elution ion exchange chromatography : One is for simultaneous elution. The eluent is a dilute acid, alkali or salt solution may be used, and an appropriate organic solvent may also be used, wherein the salt solution is mainly used, and the dosage form according to the nature of the target product and the final product is selected. Since the substance to be absorbed is often not a single species, the charge of each substance is different, and the binding strength to the medium is different. Even if the same eluent is used, the easily replaced substance will flow out of the medium first, and the binding force is strong. After the material is discharged

Electronic grade hydrogen peroxide

Image
1.  Electronic grade hydrogen peroxide Hydrogen peroxide can be used in the semiconductor grade hydrogen peroxide  industry. According to statistics, the demand for high purity hydrogen peroxide  accounts for 10%-15% of the total high-purity reagent consumption in the semiconductor industry. High purity hydrogen peroxide is also an important raw material for caprolactam. Almost all of the production of hydrogen peroxide at home and abroad uses the hydrazine method, so the hydrogen peroxide always contains a small amount of hydrazine. For example, in the production of caprolactam, the content of terpenoids increases with the operation of the apparatus, and the TOC is generally 300 ppm, which indirectly contaminates the quality of caprolactam. 2. Purification of hydrogen peroxide The purification of hydrogen peroxide is main to remove the organic carbon in the hydrogen peroxide. The strong oxidizing and instability of hydrogen peroxide has limited many common purific

Drainage water recycling

Image
Ion Exchange Technology for Water Reuse 5 Drainage water recycling  is a process of converting drainage into recycling water. The chemical industry produces sewage at various stages, removes the salts and pollutants, and makes the effluent reach the circulating water standard and reuse it, so that zero discharge of wastewater can be achieved. Domestic sewage can be used to irrigate farmland or toilet flushing after being treated by treated water recycling technology. The electroplating industry is a large amount of water, and the total amount of heavy metal ions in water is high. In recent years, the Chinese government has made specific regulations on the reuse of water in the electroplating industry. Specifically, it is necessary to stipulate the COD, metal ion content, salt concentration, pH, and color of the water. In the conventional water reuse process, the ammonia nitrogen COD in the water needs to be biochemically treated, and the dissolved salt generally needs to

Copper recovery

Image
Ion Exchange Technique for Copper Recovery  from Mines, Mining Tailings, Electroplating Copper is the first metal discovered and used by humans and is widely used due to its good ductility, thermal conductivity and electrical conductivity. Copper is widely used in electrical appliances, light industry, machinery manufacturing, construction industry, national defense and other industries, and its consumption is second only to aluminum. Copper is mainly obtained from the smelting of copper ore. The copper smelting process is divided into two types: fire method and wet method. High-grade ore is generally smelted by fire method, high-grade tailings and low-grade copper oxide, which are generally smelted by wet method. With the reduction of recoverable high-grade ore, wet smelting technology has gradually gained attention. The wet copper smelting uses copper sulfate to convert the copper element in the copper ore into soluble copper sulphate, and then puts the iron into the cop

Civil&industry water treatment

Image
I on R esin E xchange W ater T reatment , Demineralization, Harmful Ion Removal Drinking water, also known as potable water, is water that is safe to drink or to use for food preparation. Globally, by 2015, 89% of people had access to water from a source that is suitable for drinking - called improved water source. Agriculture is by far the largest water use at global level. Irrigation of agricultural lands accounted for 70% of the water used worldwide.The water quality used for irrigation is essential for the yield and quantity of crops, maintenance of soil productivity, and protection of the environment. For example, the physical and mechanical properties of the soil, ex. soil structure (stability of aggregates) and permeability, are very sensitive to the type of exchangeable ions present in irrigation waters. There are many use of resin in water treatment   and, in most cases, the used water also needs treatment to render it fit for re-use or disposal. Raw water enterin

The Classified of Ion Exchange Resin

Image
Ion exchange resin  is a kind of macromolecule compound with a functional group (an active group of exchange ion), network structure and insolubility, usually spherical particles. The has many advantages. The full name of ion exchange resin consists of classification name, skeleton (or gene) name and basic name. The pore structure is divided into two types: gel type and macroporous type. All with physical pore ion exchange resin structure  are added "big hole" before the full name. If the classification is acidic, the word "cation" should be added before the name, while the classification is alkaline, and the word "anion" should be added before the name. Such as macroporous strong acidic styrene cation exchange resin.  If you want to know the application of ion exchange resin  or buy ion exchange resin material ,please contact us. Our ion exchange resin chemistry  is great. Sunresin is an innovation oriented high-tech enterprise. It is specialized in
