Strongly basic styrene type anion exchange resins are widely used in water treatment processes to remove contaminants such as nitrates, chlorides, and sulfates from drinking water and wastewater. They are also employed in the purification of industrial process water, ensuring the removal of harmful anions that could affect product quality or damage equipment.

In the pharmaceutical industry, these resins play a crucial role in the purification of active pharmaceutical ingredients (APIs) by selectively removing impurities and unwanted ions. They are also utilized in the production of high-purity water required for drug formulation and manufacturing.

Additionally, these resins are used in the sugar industry for decolorization and demineralization of sugar syrups, improving the quality and taste of the final product. In the nuclear industry, they assist in the removal of radioactive anions from waste streams, contributing to safer waste management practices.

Their ability to selectively exchange anions makes them valuable in various chemical synthesis processes, where they are used to catalyze reactions or separate specific ions from mixed solutions. Overall, their versatility and efficiency make them essential in numerous industrial and environmental applications.
