What is the role of ion exchange resins in human survival and environmental protection in Sichuan?

Ion exchange resin is a kind of macromolecule compound with spherical particles. Ion exchange resin has been applied in environmental protection. It can neutralize toxic ions or non-ionic substances in aqueous or non-aqueous solutions, thereby reducing the harm of toxic substances to the environment.

The recycling of these neutrals also reflects the goal of sustainable development. The acidic cations and basic anions contained in ion exchange resin can neutralize the acidity and alkalinity of solution and adsorb heavy metal ions to form precipitation, which is easy to recover. This will greatly reduce the harm of acid-base substances or heavy metals to the environment and play a role in environmental protection.

Sichuan ion exchange resin is insoluble in water and does not harm the quality of water, but it contains a large number of hydrophilic groups and can absorb water and expand. When the ions in the resin are exchanged, the corresponding ions will be absorbed to increase the volume of the resin. So the production equipment should consider this problem. For example, removing metal ions from electroplating solutions.
