“…Some workers consider that they are present in the pickling solution in a colloidal form and are adsorbed on to the surface of the metal , thus protecting the latter from further attack by the acids ; other authors consider the retarding action of addition agents on the solubility of ametal in acids to be due to their ability to increase the hydrogen over voltage on the metal (15) .…”

The accelerating effect of 1,4- phenylenediamine (PDA) additions in 1M hydrochloric acid solution at temperature rang (20-60) C° has been studied by weight losses measurement during ranging time (1-260) h and by following the pb2+ concentration in solution after several times by using Atomic absorption spectroscopy (AAS) . The volume of hydrogen gas involving was followed also in presence and absence of (PDA) in the corrosive solution .Accelerating enhanced by adding (NaCl , NaBr , NaI ) was also investigated.

“…For the prevention of the above characteristic pit falls in chemical pickling it is recommended that certain organic and inorganic compounds , knows as etching additions , should be added to HCl solutions .

Tertiary arsines such as diphenylethyl arsine (DPEA), diphenylmethyl arsine (DPMA) and triphenyl arsine (TPA) have been used as corrosion inhibitors for zinc in perchloric acid solution. These inhibitors inhibit corrosion effectively even in traces. The percentage inhibitor efficiency o f the inhibitors are in the order DPEA > DPMA > TPA. The effect of p H and temperature on the inhibitor efficiency is studied. Steady state anodic and cathodic polarization data reveal that tertiary arsines act as interfacial corrosion inhibitors for zinc in acidic solution. The apparent free energies of adsorption of inhibitors have been reported for different possible modes of adsorption.
