摘要
制备了一种由四乙烯五胺(TEPA)多胺改性壳聚糖衍生物(TEPA-Ch),采用动电位极化曲线法研究了TEPA-Ch在1molL-1HCl介质中对碳钢的缓蚀作用。结果表明,TEPA-Ch为混合型缓蚀剂,在酸性介质中自发地吸附在碳钢表面,其吸附方式遵循Langmuir吸附等温式。
A polyamine modified chitosan derivative(TEPA-Ch) was prepared by tetraethylenepentamine(TEPA).The potentiodynamic polarization curve method was proposed to research the corrosion inhibition of carbon steel by TEPA-Ch in the medium of 1mol·L-1HCl.The results showed: TEPA-Ch was a mixed type inhibitor,it adsorbed on the surface of carbon steel in acidic medium spontaneously,the adsorption followed Langmuir adsorption isotherm.
