The inhibition efficiency of polyvinyl pyrrolidone (PVP) in controlling corrosion of carbon steel immersed in an aqueous solution containing 60 ppm of CI-, in the absence and the presence of zn2' has been evaluated by weight loss method. Influence of pH. immersion period, N-cetyl-N,N,N-trimethyl ammonium bromide and sodium dodecyl sulphate on the inhibition efficiency of the inhibitor system has also been investigated. The nature of the protective film has been analysed by FTlR and fluorescence spectroscopy. In the presence of PVP, the protective film consists of ~e- 'PV~P c omplex; the film is found to be uv-fluorescent. In the presence of PVP and zn2', the protective film consists of ~e"- PVP complex and Zn(OH),; it is found to be uv-fluorescent.
