Planned Interval Test method conducted in several intervals of times (0-5) days, (0-10) days, (0-15)) days, and (10-15) days shows the changes of environment condition and metal corrosion. The changes in the corrosiveness media and the corrosion resistant of the material. The acidity of the media gets lower from 7.6 to 7.1 in the interval of (0-5) days and the conductivity increase during the time interval. The change in acidity is caused by hydrolisis reaction and AA decomposition. During the time interval of (10-15) days a very high corrosion rate was observed due to low pH and high conductivity. The highest efficiency is found in the addition of 150 ppm AA in all different concentration of Cl - and SO4 2- in water. More or less AA concentration, AA has no function as inhibitor. The amount is not enough to form the protective film on the metal surface and some are used to form the chelate compounds with the metal ions.
