摘要研究了几种咪唑衍生物在盐酸和硫酸中对铜的缓蚀效果。电化学测试结果表明，除4-甲基-5-咪唑甲醛在盐酸中的缓蚀性能外，所研究的有机化合物均具有较好的缓蚀性能。大部分咪唑衍生物的缓蚀性能与商品铜缓蚀剂相近。水溶液对用于处理废水的生物系统的毒性的评估-如关于化学需氧量（COD）、需氧和厌氧毒性所测量的-显示所测试的抑制剂具有相对低的毒性。
Abstract The efficiency of various imidazole derivatives as corrosion inhibitors for copper in hydrochloric and sulfuric acids (HCl and H2SO4) was investigated. Electrochemical measurements showed the organic compounds investigated have fairly good inhibiting properties, except for 4-methyl-5-imidazole-carbaldehyde in HCl. Protecting properties of most imidazole derivatives were close to those of commercial inhibitors for copper. Evaluation of the toxicity of the water solutions on the biological system for treatment of waste water — as measured in regard to chemical oxygen demands (COD), aerobic, and anaerobic toxicity — showed the tested inhibitors have relatively low toxicity.
