Abstract

The Martinique island, located in the Caribbean Sea, is subject to the stranding of Sargassum algae, which decompose and release toxic gases, such as hydrogen sulfide or ammonia. This study aims to investigate the atmospheric corrosion of zinc in these conditions. For this purpose, three sites in Martinique more or less impacted by Sargassum algae stranding were selected. Mass loss results after 1-year exposure range from 1.9 µm for the site least impacted to 45.3 µm for the site most affected by Sargassum algae. This high value proves that the presence of Sargassum algae caused significant zinc degradation. The morphological structures and properties of the corrosion products obtained at the impacted and non-impacted sites differ significantly. In the absence of Sargassum algae, “classical” corrosion products based on hydrozincite, simonkoleite, gordaite, and zinc hydroxylsulfate are observed. In the area close to the Sargassum seaweed stranding, the presence of elemental sulfur products, zinc hydroxylsulfate, and sphalerite is reported.

在富含 H2S 的热带海洋环境中研究马尾藻分解对锌的大气腐蚀作用
位于加勒比海的马提尼克岛常有马尾藻搁浅,这些藻类分解后会释放出硫化氢或氨等有毒气体。本研究旨在调查锌在这些条件下的大气腐蚀情况。为此,我们在马提尼克岛选择了三个或多或少受到马尾藻搁浅影响的地点。暴露 1 年后的质量损失结果从受马尾藻影响最小的地点的 1.9 微米到受马尾藻影响最大的地点的 45.3 微米不等。这个高值证明了马尾藻的存在造成了严重的锌降解。在受影响和未受影响地点获得的腐蚀产物的形态结构和性质有很大不同。在没有马尾藻的地方,可以观察到以氢锌矿、西蒙克来石、戈尔代石和羟基硫酸锌为基础的 "经典 "腐蚀产物。据报告,在靠近马尾藻海藻搁浅的区域,存在元素硫产物、羟基硫酸锌和闪锌矿。
