At NINGBO INNO PHARMCHEM CO.,LTD., we believe in empowering our clients with knowledge about the technologies they employ. Today, we’ll explore the fascinating chemistry behind our high-performance macroporous chelating ion exchange resins and how they achieve exceptional selective boron removal.

Boron, in its most common form in water, is the borate ion. The challenge in removing it lies in its relative small size and its ability to exist in various anionic forms depending on the water's pH. Traditional anion exchange resins can remove borates, but their selectivity is often limited, especially in the presence of high concentrations of other anions like sulfates or chlorides. This is where chelating resins offer a significant advantage.

Our specific macroporous chelating ion exchange resin utilizes a functional group called meglumine. Meglumine is a derivative of glucose and sorbitol, and it possesses a unique structure with multiple hydroxyl groups and a tertiary amine. This structure is ideal for chelation – a process where a molecule forms multiple bonds with a metal ion or, in this case, a complex anion like borate. When water containing borate ions passes through the resin bed, the meglumine groups selectively bind to the borate, forming stable complexes. This chemical reaction is highly specific, ensuring that the resin primarily targets boron, leaving other ions largely unaffected.

The macroporous nature of the resin plays a crucial role. It provides an extensive internal surface area and large pore channels, allowing the borate ions to access the chelating sites more readily and efficiently. This leads to faster adsorption rates and higher overall capacity compared to non-porous or gel-type resins. NINGBO INNO PHARMCHEM CO.,LTD. has engineered this resin to maximize the interaction between the functional groups and the target contaminant, ensuring superior performance in boron removal in industrial water and drinking water applications.

The regeneration process also involves specific chemistry. Once the resin is saturated with boron, it can be regenerated using an acidic solution. The acidic conditions break the chelation bonds, releasing the boron and restoring the meglumine groups to their active state, ready for another cycle of boron removal. This cyclical capability makes the resin a cost-effective and sustainable solution for long-term water purification needs.

Understanding this chemistry highlights the advanced engineering behind our products. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing solutions that are not only effective but also based on sound scientific principles, ensuring the highest quality water for all applications.
