The protective properties of lubricating materials for galvanized cables can be evaluated according to the amount of build-up of the corrosive products ions of the metal in the lubricants over a determined period of time. In the reported work, dry ashing and extraction were used for the transfer of zinc from the lubricant to the aqueous solution. In the aqueous solution zinc was determined by complexometric titration, extraction titration with a solution of dithizone in carbon tetrachloride, and polarographically.
