Monoalkylphosphates as cathodic and anodic inhibitors of steel corrosion in a 3% wt NaCl aqueous solution

Written by sctunisie no comments

Monoalkyl disodium phosphates salts RPO4Na2, when used at 10-2 and 5.10-2 molar concentration, act as efficient cathodic and anodic inhibitors of corrosion of steal in a 3% wt NaCl aqueous solution. Inhibition mechanism involves fixation of hydrophilic groups on the metal sites and so hydrophobic groups block oxygen diffusion towards the metal.
