Abstract

Sargassum latifolium extract was used as new extract for the protection of Al dissolution using chemical and electrochemical methods. It was extracted, tested, and its high inhibition quality with addition of 1 × 10^–2 M KI at 298 K for 300 ppm in 1M hydrochloric acid was recorded. The adsorption mechanism agreed with the Temkin isotherm from the weight loss procedure. From Tafel extrapolations showed that the used extract acts as mixed inhibitor. The thermodynamic parameters were organized and clarified. The attenuated total reflectance-Fourier transform infrared spectroscopy and atomic forced microscopy were performed for the Al surface analyses and a good decrease in the surface roughness was reached. The used extract has also demonstrated a satisfying biological activity against bacterial growth.

马尾藻提取物作为 1 M 盐酸介质中铝的安全缓蚀剂：表面分析和生物学效应

摘要

马尾藻提取物被用作使用化学和电化学方法保护铝溶解的新提取物。经提取、测试，添加1× ^10-2记录 298 K 下 300 ppm 在 1M 盐酸中的 M KI。吸附机制与重量损失过程中的 Temkin 等温线一致。从 Tafel 推断表明，所使用的提取物充当混合抑制剂。组织和阐明了热力学参数。对铝表面分析进行了衰减全反射-傅立叶变换红外光谱和原子力显微镜，并达到了表面粗糙度的良好降低。使用过的提取物还显示出令人满意的抗细菌生长的生物活性。
