摘要
用失重法研究了盐酸溶液中苯扎溴胺对锌的缓蚀作用,发现苯扎溴胺在锌表面上的吸附是产生缓蚀作用的重要原因,且吸附规律服从Langmuir吸附等温式.用Sekine方法处理实验数据,获得了吸附过程ΔH0、ΔS0和ΔG0等重要热力学参数.
The corrosion inhibition of dodecylbenzyldimethylammonium bromide on zinc in hydrochloric acid was investigated by weight - loss method. It was found that the adsorption of dodecylbenzyldimethylammonium bromide on the surface of zinc plays important roll for its corrosion inhibition and that the rule of adsorption follows langmuir＇ s isotherm. The experimental data were treated with sekine method. Some thermodynamic parameters, such as △H^0、△S^0 and △G^0, are obtained.
