SEPLITE ® Weak Base Anion Exchange Resin

The Weak Base Anion Exchange Resin with primary, secondary, tertiary amine or mixed amine group as active functional groups show different strengths of alkalinity. Most weak Base Anion Exchange Resins with mixed amine group equiped a extremely high operating capacity with the ability to remove both strong and weak acids from solution.

There are two kinds of weak base anion exchange resins, Gel type and Macroporous type, which have acrylic backbone, styrene backbone or mixed backbone. Weak base anion exchange resins are more chemically stable and higher resistant to organic fouling than strong base anions.

The weak base anion exchange resin is easier to regenerate than the strong base resin, and can be efficiently regenerated with a small amount of sodium hydroxide.

Weak base anion exchange resins are commonly used in pharmaceutical, food engineering, and chemical engineering, such as the removal of mineral acid, organic acids and other organic materials, especially for removal of high molecular weight organic matters from aqueous solutions under low pH condition.

Separation Technique Based on Ion Exchange & Adsorption

Stevioside extraction and purification is mainly extracted from the roots and leaves of stevia leaves, with the highest content of stevioside in leaves. Its sweet taste mainly consists of stevioside A, B, C, D, E. Stevioside can be extracted with water, and after clarification and crystallization, extracts of different purities can be obtained.

Stevioside is 250-450 times sweeter than sucrose, but because of the presence of stevioside A, it has a distinct bitter taste and astringency.

Our technology in stevioside extraction is based on the principle of ion exchange and adsorption, using a series supporting separation system to achieve extraction, decolorization, demineralization, purification and other important steps. Our technology has achieved great success in China.

Sunresin has conducted in-depth research in the field of stevia refining. Sunresin once hosted the China Stevia Industry Technical Exchange Conference and achieved great success. China's stevia manufacturers like to work with Sunresin and continue to accelerate their industry upgrades through Sunresin's technology.

SEPLITE ® Strong Base Anion Exchange Resin

The Strong Base Anion Exchange Resin (sba resin) is the type of ion exchange resin with functional group of quaternary ammonium, which is strongly alkaline and dissociates just like NaOH and KOH.

In chemical structure, there are two types of strong base anion exchange resin with different alkalinity strengths, Type Ⅰ with a trimethyl ammonium group, Type Ⅱ with a dimethylethanol ammonium group. Type Ⅰ shows a higher alkaline than Type Ⅱ. Compared with type 1 strong base anion, this resin is more suitable for applications needing good rinsing performance and excellent regeneration efficiency.

The strong base anion  shows an excellent physical and chemical stability, which is capable of exchanging the different anion under a wide range of pH.

The Strong Base Anion Exchange Resin is mainly used in water treatment, to produce high purity demineralized water, making use of the ability to adsorb anions strongly.

Typical Applications For Strong Base Anion Exchange Resins

Sugar purification

Antibiotics purification

Organic removal

Industrial demineralization

Silica removal

Pure water preparation

Metal extraction

Condensate deionization

Periodic Table Resin

Lanthanides

The lanthanide series of chemical elements comprises the fifteen metallic chemical elements withatomic numbers 57 through 71, from lanthanum through lutetium . These fifteen lanthanide elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements.

Actinides

The actinide series encompasses the 15 metallic chemical elements with atomic numbers  from 89 to 103, actinium through lawrencium.The actinide series derives its name from the first element in the series, actinium.They all have very large atomic andionic radii and exhibit an unusually large range of physical properties. While actinium and the late actinides (from americium onwards) behave similarly to the lanthanides, the elements thorium through neptunium are much more similar to transition metals in their chemistry.
