PROBLEM TO BE SOLVED: To provide an acidic gas treatment agent which is capable of suppressing problems caused by ammonia gas, while maintaining or improving the fluidity of sodium hydrogen carbonate, a method for producing the acidic gas treatment agent, and an additive for acidic gas treatment agent.SOLUTION: An additive for an acidic gas treatment agent is composed of an aluminosilicate salt and is used for the removal of ammonia gas that is released from sodium hydrogen carbonate. A method for producing an acidic gas treatment agent comprises a step wherein the aluminosilicate salt and sodium hydrogen carbonate are mixed, and pulverized for formulation. The acidic gas treatment agent contains sodium hydrogen carbonate and the aluminosilicate salt in an amount of 0.1-10 mass% relative to the sodium hydrogen carbonate. |
