The paper vividly demonstrates that dissolved oxygen can be virtually completely removed from corrosive medium by sodium sulfite chemical reduction. We propose the express-method for oxygen removal from formation water sample solution and other corrosive media by sodium sulfite chemical reduction of oxygen. Using the corrosive media samples of the Ural-Volga region, the paper proves the efficiency of the method for chemical removal of the dissolved oxygen from the solution and expediency of its application in corrosion tests.
