Used in water treatment to remove organic acids and weakly ionized acidic contaminants due to its high surface area and selectivity for large anions. Effective in decolorizing sugar solutions and purifying pharmaceuticals by adsorbing colored impurities and organic by-products. Commonly applied in the recovery of valuable organic acids from industrial effluents. Suitable for continuous ion exchange processes because of its robust macroporous structure and good mechanical strength. Also utilized in the food industry for deacidification and purification of juices and alcoholic beverages.
