本文利用比色法研究低碳钢在硫酸中腐蚀的初速度。由初速度与浓度的关系,可以推导出一个反应动力学表示式,即r_0=K·e~(BC),用阿氏方程K=Ac~(-E/RT)代入,得r_0=A·c~(BC)·e~(-E/RT)。经实验求出此动力学表示式中各参数。
This paper uses colorimetric method to study the initial velocity of mild steel corrosion in sulfuric acid. From the relationship between the initial velocity and the concentration, a reaction kinetic expression can be deduced, that is r_0 = K · e ~ (BC), and substituted by the equation of K = Ac ~ (-E / RT) c ~ (BC) · e ~ (-E / RT). The kinetic expression of the parameters obtained by experiment.
