Potentiostatic study for the effect of las on the corrosion of pure zinc in 0.01 m hcl solutions

Abstract EN

A potentiostatic study for the corrosion of pure zinc in 0.01 M HCl was achieved in absence and presence of (linear alkyl benzene solfonate LAS) detergents in a range of concentrations (0-50) mg / L.

The electrochemical studies included anodic, cathodic polarization by using potentiostatic over temperature rang (293- 323) K.

The mechanism of corrosion rate of pure zinc was suggested by evaluating of αa, αc, ba, bc, i0, Rp and the kinetic parameters also calculated (Ea, A) at the above temperature range, The thermodynamic of corrosion, corrosion accelerating and corrosion protecting were investigated by calculating (∆G, ∆H and ∆s) values.
