This invention relates to the field of flue gas treatment technology, specifically to a sulfur dioxide gas absorbent, comprising the following raw materials by weight: 90-100 parts of an aqueous amine solution and 2-6 parts of additives. In this invention, the nitrogen-zinc ion-sulfur active center of the catalyst acts as a molecular key, efficiently and reversibly coordinating and activating sulfur dioxide molecules, significantly reducing the reaction energy barrier and fundamentally improving the intrinsic absorption rate. The enhancer, with its high specific surface area, provides a large interface for the reaction. Its surface sulfonic acid groups not only buffer the decrease in system pH, maintaining the optimal acid-base environment for the reaction, but also catalyze the conversion of absorption intermediates into more stable products, thereby shifting the reaction equilibrium to the right. Under the combined effect of these two factors, the catalyst accelerates the reaction towards equilibrium, while the enhancer continuously shifts the equilibrium point, resulting in a higher absorption capacity for the absorbent.
