The invention provides a method for desorbing an acidic gas by an oxidization process and relates to desorption of SO2 and NO(x) in a CO2 system. The acidic gas consisting of the SO2 and the NO(x) is oxidized by hydrogen peroxide serving as an oxidant and dissolved in water to form acid, so that the acidic gas can be separated from other gases. According to the concentration of the acidic harmfulgas in the system, a suction process and an absorption process are adopted respectively. As the CO2 does not take part in the reaction, the load of the deacidified gas as well as the investment and energy consumption cost are reduced. The acidic solution is converted into a fertilizer after being treated by ammonia water, so that secondary pollution is avoided and an additional value of the process is increased; therefore, the method is particularly suitable for desorption of a little of sulfur oxide and nitric oxide.
