66530-440 The invention comprises a method for determining the corrosion rate of metals in contact with a liquid system which is capable of causing corrosion of such metals which comprises adding to the liquid system an electrochemically active compound having a reduction potential more positive than the metal in contact with the liquid system and then monitoring the system thus treated with the electrochemically active compound to determine its rate of reduction which is proportional to the corrosion rate of the metal. Preferably the electrochemically active compound is a tetrazolium compound having the structural formula: wherein R1, R2, and R3 are from the group consisting of lower alkyl, aryl, aralkyl, thiazol-2-yl substituted aryl with the proviso that neither R1, R2, or R3 contain more than 14 carbon atoms and n may be 1 or 2. |
