摘要
用分光光度法研究了OP对Ni在盐水中的缓蚀作用,应用吸附理论和Sekine方法处理实验数据,发现OP在Ni表面发生了吸附并服从Langmuir吸附等温式.求得吸附热为52.29kJ·mol-1,可以认为这种吸附是产生缓蚀作用的主要原因.
The inhibitory effect of nickl caused by OP (p-octyl polyethylene glycol phenyl ether) in sodium chlorid solution has been studed by spectrophotometric method. The experimental results are explained with adsorption theroy and Sekine's method. It is sugestide that OP is adsorpted by the surface of nickl in acidic sodium chloride solution. The adsorption obeys Langmuir's isotherm and is the main cause of inhibition. The experimental adsorption heat is 52. 29 kJ/mol.
