摘要
用电化学方法测定了异喹啉及其衍生物的缓蚀效率,用HMO、CNDO法作量子化学计算表明:随着N原子负净电荷的减少,缓蚀效率提高;随异喹啉分子的吡啶环负净电荷增大,缓蚀效率也得以提高。根据实验和计算的结果,提出了这类缓蚀剂在HCl溶液中以平卧方式吸附于金属表面的模型。
Abstract The structure parameters and corrosion inhibition of isoquinolines were determined by HMO,CNDO and electrochemical methods. The results showed that the inhibition efficiency increases with the decrease of ne\{gat\}ive net charges of N atom and pyridine ring. We \{sug\}gest that the molecules of inhibitors are adsorbed on the surface of Fe electrode in horizontal state.
