摘要
用失重法研究了土酸溶液中苯扎溴铵对黄铜的缓蚀作用,发现苯扎溴铵在黄铜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Langmu ir吸附等温式。用Sek ine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 benzalkonium bromide on brass in mud acid was investigated by weight-loss method. It was found that the adsorption of benzalkonium bromide on the surface of brass is the important reason resulted from corrosion inhibition and that the rule of adsorption conforms with Langmuir＇ s isotherm. The experimental data were treated with Sekine method. Some thermodynamic parameters, such as △H°、△S°and △G° were obtained.
