The product "High Quality amberlite(r) xad-4 cas 37380-42-0 With Best Price" is a high - quality resin product. Amberlite XAD - 4 is a non - ionic, macroporous polymeric adsorbent. The CAS number 37380 - 42 - 0 uniquely identifies this chemical compound in the chemical registry.
Some of its basic parameters include a high surface area, which allows for efficient adsorption. It has a consistent pore size distribution, ensuring reliable performance in various applications. The resin is mechanically stable, which means it can withstand the physical stresses during the adsorption and desorption processes.
This product has a wide range of applications in different industries. In the environmental field, it is used for the removal of organic pollutants from water sources. For example, it can adsorb aromatic compounds, pesticides, and other organic contaminants, helping to purify water and make it safe for human consumption or industrial reuse.
In the pharmaceutical industry, it is used for the purification of drugs and active pharmaceutical ingredients (APIs). It can selectively adsorb impurities and by - products, improving the quality and purity of the final pharmaceutical products.
In the food and beverage industry, it can be used to remove unwanted flavors and odors from products. For instance, it can adsorb off - flavors in fruit juices or wines, enhancing the sensory quality of these products.
Before using the amberlite(r) xad - 4, it is necessary to pre - treat the resin. This usually involves rinsing the resin with an appropriate solvent to remove any manufacturing residues or impurities. The pre - treatment process can vary depending on the specific application and the nature of the contaminants to be removed.
The adsorption process typically involves passing the liquid containing the target substances through a column packed with the amberlite(r) xad - 4 resin. The flow rate should be carefully controlled to ensure optimal contact time between the liquid and the resin. After the adsorption is complete, the resin can be regenerated for reuse. Regeneration usually involves using a suitable desorbent to remove the adsorbed substances from the resin.
Water Treatment in a Municipal Water Plant: A municipal water plant was facing high levels of organic pollutants in its raw water supply. They decided to use amberlite(r) xad - 4 for treatment. First, they pre - treated the resin with deionized water. Then, they packed the resin into a large - scale adsorption column. The raw water was passed through the column at a controlled flow rate. After treatment, the levels of organic pollutants in the water decreased significantly, meeting the drinking water standards. The resin was regenerated by using a methanol - water mixture, and it could be reused multiple times.
Pharmaceutical Purification in a Drug Manufacturing Company: A drug manufacturing company was producing an API that was contaminated with some by - products. They used amberlite(r) xad - 4 for purification. The resin was pre - treated with ethanol. The API solution was passed through a small - scale column packed with the resin. The impurities were adsorbed by the resin, and the purified API was collected at the outlet. The resin was regenerated with a sodium hydroxide solution, and the purity of the API increased from 90% to over 99%.
