摘要

采用失重法研究了甜瓜(Cucumismelo)(MPE)和花生(Arachishypohaea)果皮提取物(GPE)在常温下对2M盐酸溶液中低碳钢的缓蚀作用。GPE和MPE对2m HCl浓度的抑制率分别为94.40%和92.64%。总的来说,在不同浓度的HCl溶液中,联片的失重量减小,而抑制剂(MPE和GPE)的缓蚀效率随着抑制剂浓度的增加而增加。关键词:黄瓜,花生,腐蚀,抑制剂

Melon ( Cucumismelo ) and Groundnut ( Arachishypogaea ) peel extracts as corrosion inhibitors for mild steel in hydrochloric acid solution
The corrosion inhibition of mild steel in 2M hydrochloric acid solution by Melon ( Cucumismelo )(MPE) and Groundnut ( Arachishypohaea ) peel extracts (GPE) at room temperature has been investigated using weight loss method. Inhibition efficiencies of 94.40% and 92.64% for2M HCl concentration was observed for GPE and MPE respectively. Generally, the weight loss of the coupons decreases at different concentrations of HCl solutions while the inhibition efficiencies of the inhibitors (MPE and GPE) increased with increasing inhibitor concentrations. Keywords: Cucumismelo, Arachishypogaea , corrosion, inhibitors
