What Are The Types And Uses Of Macroporous Adsorption Resins

Macroporous adsorption resin is a material with a porous structure and a large specific surface area, so it is more suitable for use in some adsorption and separation industries. At present, there are more types of macroporous adsorption resins used, and their uses are also relatively extensive. Let's take a look at it through this article.

Macroporous adsorption resin types
Organic polymer skeleton resin: This type of macroporous adsorption resin is the most common one, its skeleton structure is composed of polymer chains, and according to its functional groups can also be divided into several small categories:
1. Amine formate resin: It is a resin with amine group and formate group, which can adsorb some acidic substances.
2. Styrene resin: This kind of macroporous resin has styrene units, mainly adsorbing organic matter.
3. Acrylic resin: This is a kind of macroporous resin with acrylic unit, which can adsorb organic matter and heavy metal ions.

Inorganic skeleton resin: It is another common type of macroporous adsorption resin, and the skeleton structure is composed of inorganic materials such as silica gel, alumina, and aluminum silicate. According to its functional group properties, it can be divided into the following types:
1. Silicone resin: large porous resin with silicone skeleton, mainly adsorbed water and organic matter.
2. Alumina resin: large porous resin with alumina skeleton, which can adsorb acidic substances and heavy metal ions.
3. Aluminum silicate resin: large porous resin with aluminum silicate skeleton, which can adsorb organic matter and heavy metal ions.

Use of macroporous adsorption resin
1. Water treatment: In the water treatment industry, macroporous adsorption resin is the most commonly used field, which can absorb organic matter and impurities in water, so that production or domestic water can meet the corresponding standards.
2. Pharmaceutical industry: Macroporous adsorption resin can extract the active ingredients used in plants for pharmaceutical production, and is used for purification and purification in pharmaceutical production.
3. Food industry: It is used to remove harmful substances in food and cover the quality of food, such as decolorization, deodorization, bitter, salty and other processing in food production, or the quality and taste in the production of juice, drinks, alcohol and so on.
4. Chemical industry: Macroporous adsorption resins are used to absorb liquids and solvents, such as catalysts and catalyst carriers.
5. Environmental protection: suitable for the purification of industrial and domestic wastewater, such as it can absorb and recycle heavy metal ions in wastewater.
