Ion Exchange Resin Activation

Ion exchange resin contains a certain amount of water, which should be kept as much as possible during transportation and storage. If the resin is dehydrated during storage, it should be soaked in concentrated salt water (about 10%) and then diluted gradually. The resin should not be directly put in water to avoid rapid expansion and crushing.

 

In long-term storage, strong resin should be changed into salt type, weak resin can be changed into hydrogen type or free alkali type, or salt type, and then immersed in clean water. During storage or transportation, resin should be kept in a temperature environment of 5-40 degrees C to avoid supercooling or overheating and affect quality. If there is no insulation equipment in winter, the resin can be stored in salt water, the concentration of salt water can be determined according to the temperature.

 

The industrial products of ion exchange resins often contain a small amount of oligomers and monomers that do not participate in the reaction, and also contain inorganic impurities such as iron, lead and copper. When the resin is in contact with water, acid, alkali or other solutions, the above substances will be transferred into the solution, affecting the quality of the effluent. Sunresin is a professional manufacturer of ion exchange resin China. If this happens, you can consult it.

 

Ion exchange resins are easily polluted by suspended substances, colloidal substances, organic substances, bacteria, algae, iron and manganese in long-term use, resulting in the reduction or even loss of ion exchange capacity. Therefore, the resin should be activated periodically according to the situation, and the activation method can be determined according to the pollution situation and conditions. You can also contact Sunresin for a detailed solution.8466655061?profile=original

Weak Acid Cation Exchange Resin (WAC)

What is weak acid cation?

 

SEPLITE ® Weak Acid Cation Exchange Resin

 

The acidic ion exchange resin is the type of ion exchange resin with functional group of carboxylic acid group (-COOH) . They show weak acidity like acetic acid, having the ability to exchange with bases such as NaOH and weak acid salts such as NaHCO3.

 

The weak acid cation exchange resins have two kinds of chemical structures, a methacrylic acid type and an acrylic acid type. This makes a difference for the ion exchange ability. The methacrylic acid type can be used at pH above 5, while the acrylic acid type can be used at pH above 4. Even though use is restricted, it is easier to regenerate than a strong acid cation exchange resin.

 

Weak acid cation resins are suitable in the fields of removal of water dealkalization, carbonate hardness, purification of antibiotics and amion acid. It is not used much for water processing because of the less acidity, but for antibiotic and amino acid purification.

 

Typical Applications For Weak Acid Cation Exchange Resin

Bicarbonate alkalinity from water

Transition metals recovery

Water dealkalization

Purification of antibiotics and amion acid

Approvals

Kosher Certificate

Halal Certificate

FDA registeration

WQA Gold Seal Certificate

REACH

Sieber Resin

9-Fmoc-Aminoxanthen-3-yloxy-polystyrene resin

A hyper acid-labile linker or the Fmoc SPPS of protected amides via mild 1% TFA cleavage. The sieber amide resin can be readily reductively alkylated to provide a support suited to the synthesis of secondary carboxamides. This resin has also been employed to produce protected peptide fragments in wich the C-terminal carboxylic acid group is blocked as a hydroxymethylphenoxy-β-alaninamide ester.
