Abstract

Tin is a moderately corrosion resistant material that is widely used in tinplate for food beverages. However, despite its excellent corrosion resistance, the presence of oxidizing agents enhances tin dissolution. Dissolution of metallic tin, especially from the inside of a can body into the food content has a major influence on the food quality and may cause toxicological effects. To overcome the problem, different chemical compounds are added. The most utilized inhibitors in the food industry are nitrites and nitrates well-known as hazardous to health. The present study aimed to investigate the influence of carboxylic acids on the corrosion resistance of tin since they are present in fruit juices and different foodstuffs. The corrosion protection efficiency of the carboxylate coatings was investigated in a sodium chloride solution using electrochemical and spectroscopic techniques. The structural characteristics of the surface coatings were investigated using the FTIR spectroscopy and optical microscope.

几种羧酸对锡在氯化钠溶液中的防腐作用

锡是一种中等耐腐蚀材料，广泛用于食品饮料马口铁。然而，尽管它具有优异的耐腐蚀性，但氧化剂的存在促进了锡的溶解。金属锡的溶解，特别是从罐头内部进入食品的含量，对食品质量有重大影响，并可能造成毒理学效应。为了克服这个问题，添加了不同的化合物。食品工业中使用最多的抑制剂是众所周知对健康有害的亚硝酸盐和硝酸盐。本研究旨在探讨羧酸对锡的耐腐蚀性的影响，因为它们存在于果汁和不同的食品中。采用电化学和光谱技术研究了羧酸盐涂层在氯化钠溶液中的防腐效果。利用红外光谱和光学显微镜研究了涂层的结构特征。
