description	The present invention discloses an ammonia gas recovery method, a concentration measurement method of ammonium sulfate solution, and a concentration control method of ammonium sulfate solution. The ammonia gas treatment method of the present invention provides 1-98% by weight of sulfuric acid as the reactant and carries out batch-wise reaction of continuous reaction between the reactant and the ammonia gas to produce 1-73% by weight of the ammonium sulfate solution, thereby providing the ammonium sulfate solution with high concentration and obviating the drawbacks in prior arts where the ammonia gas is dissolved in water to result in difficult recovery and where the recovery must be followed by the concentration treatment. The concentration measurement method of ammonium sulfate solution of the present invention can, according to the pH value alone or the pH value and conductivity of the ammonium sulfate solution, determine whether the weight percent concentration of the ammonium sulfate solution is in compli
