Abstract
The invention relates to a method for removing aromatic sulfonic acid anions in an aqueous solution and an aromatic sulfonic acid anion CMOFs material, and belongs to the field of sewage treatment. According to the method, an ATRZ aqueous solution and an inorganic metal salt aqueous solution are dropwise added into a sewage solution containing aromatic sulfonate anions, and high-crystallinity water-insoluble CMOFs crystals taking the aromatic sulfonate anions as balanced anions are formed by virtue of coordination interaction, so that the aromatic sulfonate anions in the aqueous solution are effectively removed. The method is easy to operate and mild in condition, is suitable for aromatic sulfonate anions containing different groups, and has high selectivity.
