Generally phosphates, chromates, nitrites and zinc ions are used as inhibitors in the older days. In order to reduce the usage of these hazardous substances, now a days phosphonates are used as green inhibitors for sustainability of potable water. The need of the hour is to develop formulations free from hazardous materials used in potable water system. In our studies, we developed the formulation which acts as eco - friendly inhibitor.Keywords

Corrosion rates of carbon steel immersed in various concentrations of Cl- (100 ppm and 150 ppm) have been evaluated by weight loss method in the absence and presence of Amino (trimethylene phosphonic acid) ATMP and Zn2+. It is found that ATMP alone is corrosive at 100 ppm Cl- but at 150 ppm Cl- it shows some inhibition efficiency (IE) due to deposition of Cl- on metal surface. However interestingly, ATMP shows very good IE in the presence of Zn2+ at all concentrations of Cl-. A synergistic effect is noticed between ATMP and Zn2+. The protective film has been analysed by surface analysis techniques and a suitable mechanism of corrosion inhibition is proposed.
