weakly basic acrylic acid type anion exchange resin - Introduction
Open Data Unverified Data
Weakly basic acrylic anion exchange resin is a high molecular compound with the following properties:
1. Weakly alkaline: The resin has a certain degree of alkalinity and can be exchanged with anions in acidic substances (such as Cl-, SO42-, etc.).
2. High adsorption capacity: The resin has a high adsorption capacity, which can effectively absorb and remove anionic pollutants in the solution.
3. High temperature resistance: The resin can maintain stability and adsorption performance at higher temperatures.
The main uses of weak basic acrylic anion exchange resins include:
1. Water Treatment: used to remove anionic pollutants in water, such as nitrate, chloride ions, etc.
2. Pharmaceutical field: purification process used in the preparation of drugs and biological agents.
3. Industrial field: for the separation and purification of anionic impurities in chemicals and optoelectronic materials.
The preparation method of weak basic acrylic anion exchange resin includes:
1. Polymerization method: By polymerizing acrylic monomer and crosslinking agent, resin particles with exchange performance are obtained.
2. Functionalization: On the basis of the existing acrylic exchange resin, functional groups with basic groups are introduced through functional modification.
When using and operating weakly basic acrylic anion exchange resin, the following safety precautions should be paid attention:
1. Avoid inhalation: During operation, avoid resin dust inhalation nose to avoid irritation to the respiratory system.
2. Avoid contact with skin: Wear gloves and avoid direct contact with the skin to avoid allergy or irritation.
3. Avoid eating: resin has a high molecular weight, can not be eaten, so as not to cause adverse effects on health.
4. Storage Note: The resin should be stored in a dry, cool, well-ventilated place, and away from fire and oxidizing agents.
In the specific use process, it is necessary to refer to the safety data sheet and operation manual provided by the resin supplier for reasonable use according to the specific situation.
