Despite the high inhibition efficiency of various synthetic inhibitors most of them are not safe and produce dangerous wastewaters which are harmful for the ecosystem and human health. Therefore, the use of cost-effective and eco-friendly corrosion inhibitors have attracted the high consideration of researchers. One of the most important classes of eco-friendly corrosion inhibitors is the extract of different parts of plants. The extracts obtained from natural sources consist of a large amount of various chemical constituents containing aromatic rings, carbonyl (-C=O), carboxylic (-COOH), hydroxyl (-OH) and amine (-NH, -NH2) group. As a result, these compounds can be potential inhibitors forretarding the corrosion process of mild steel in acidic media. There are a large number of reports on the use of green corrosion inhibitors based on the extracts of plants. This study aims to investigate the inhibition performance of an ethanol extract of apricot cake (ACE) on the corrosion of mild steel in 0.5 M NaCl under different experimental conditions. The present study was carried out to identify the components present in the ethanol apricot cake extract by GC-MS analysis.
