Corrosion inhibito r and germicide(PS -12)w hich is a quarternary ammonium salt and has the phosphono-and carboxy g roups, has been studied.The experiment results of the weight loss and polarization experiments show that PS-12 is an excellent corrosion inhibito r for iron in the simulating cooling water.It is found that P-12 belongs to the mixing inhibito r fo r it can block both the anodic and the cathodic reaction.The results of XPS analyses demonst rate that a layer of film is formed when PS-12 chelates Fe2+and Ca2+, and the film grows more completely and compactly w ith the time increasing.The germicidal testing results show that PS-12 has excellent germicidal ability.
