The invention discloses a preparation method of iron removal powder for removing iron ions in an electronickelling bath solution, which comprises the following steps: step 1, taking raw materials: taking a reducing agent A and a reducing agent B as raw materials, and weighing a certain amount of the reducing agent A and the reducing agent B for later use; a certain amount of reducing agent A is added into the stirring equipment, then a certain amount of reducing agent B is added into the stirring equipment, the mixture is fully stirred for 30 min, and after the reducing agent A and the reducing agent B are evenly dispersed, a finished product with iron powder removed can be prepared, and 3, finished product testing is conducted, specifically, three hundred milliliters of nickel plating solution containing third-order iron ions is taken. According to the invention, ferric ions are reduced into divalent ions, then the divalent ions are chelated, precipitated and filtered, the powder is simple in proportioning,
