摘要
采用失重法研究了在0.8mol/dm3盐酸中,盐酸吖啶和溴代十六烷基吡啶对锌的缓蚀作用,求得相关吸附热力学参数。结果表明二者均对锌表现出较强的缓蚀作用,盐酸吖啶在锌表面的吸附属于放热反应,而溴代十六烷基吡啶在锌表面的吸附属于吸热反应。
The corrosion inhibition efficiency of acridine hydrochloride and bromocetylpyridine on zinc were investigated using the weight loss method in 0,8 mol/dm^3 hydrochloric acid solution. The thermodynamics parameters of adsorption were determined. It was shown by the results that the corrosion inhibitors were high efficiency on zinc. The adsorption of acridine hydrochloride on zinc was an exothermic reaction, but the adsorption of bromocetylpyridine on zinc was an endothermic reaction.
