Method for removing manganese in manganese-containing acidic solution

The invention belongs to the technical field of chemical manganese removal, and particularly relates to a method for removing manganese in a manganese-containing acidic solution. The method comprisesthe following steps: adding a hydroxyl radical inhibitor into a manganese-containing acidic solution, introducing ozone, heating, standing, and filtering to obtain a manganese-removed acidic solution.According to the method for removing manganese, the hydroxyl radical inhibitor is added into the manganese-containing acidic solution and then ozone is introduced; the hydroxyl radical inhibitor canreduce the dissolving speed of ozone in the acid solution, so that the existing life of ozone in the acid solution is prolonged, the utilization rate of ozone is increased, and the purposes of reducing the ozone consumption and improving the Mn < 2 + > removal efficiency are achieved. According to the method, the manganese removal efficiency of ozone can be improved, the production cost is reduced, introduction of new impur
