Abstract: Corrosion kinetics of Fe0 in aqueous at pH 2 is controlled by the transport step of products from redox reaction through a liquid film layer from iron surface to bulk solution which can be represented by the following equation: d[Fe2+]/dt = 5.9x[Area]xt-1/2. Where “d[Fe2+]/dt” is in mg.l-1, “{Area]” is area concentration of Fe0 in m2.l-1. “t” I s time in min, and the rate constant in mg.m2.min-0.5. The redox research of Fe0 with Cr(VI) is more rapid than that with water and is the first order with respect to Cr (VI) and Fe0 surface area concentrations: hence, the second order overall as follows: …
