D301 Macroporous Styrene Series Weak Alkaline Anion Exchange Resin
About this Product:
This is a weak alkaline anion exchange resin with a tertiary amine functional group within a styrene-divinylbenzene copolymer matrix. It is engineered to effectively remove organic coloring matters, inorganic acids, and silicates from acidic to near-neutral solutions.
The resin’s structure and properties make it highly versatile. It can adsorb large-sized impurities and is suitable for use in non-aqueous solutions. Key features include a highly efficient regeneration capability, large exchange capacity, strong contamination resistance, and excellent physical strength.
Application
This resin is a versatile and efficient solution, primarily used for purification and decolorization in the food and beverage industry. Its key applications include:
Water Treatment: Used for manufacturing pure water and high-purity water, and for specialized processes like the electroplating of chromium from wastewater.
Sugar Processing: Purification, ash removal, and decolorization of sugar solutions, as well as the decolorization of xylose and the desalination and decolorization of starch sugar.
