本文通过测定Armco铁在0.5mol.dm~(-3)H_2SO_4溶液中的Tafel曲线,研究了30～90℃温度区间硫脲在Armco铁上的吸附行为,并通过对实验结果的分析得出相应的吸附等温式,确定了吸附Gibbs自由能等热力学函数。
In this paper, the Tafel curve of Armco iron in 0.5mol.dm -3 H_2SO_4 solution was measured to study the adsorption behavior of thiourea on Armco iron in the temperature range of 30 ~ 90 ℃. The analysis of the experimental results Adsorption isotherm, the thermodynamic functions such as Gibbs free energy adsorption were determined.
